You would measure the Swimming Pools length, width and depth to determine how many cubic feet of water is in the swimming pool. Length x Width x depth = cubic feet. Then measure the mass of 1 cubic foot of water by building a box 1'x1'x1'. Once you know the mass of 1 cubic foot of water - you'll know the mass of the water in the swimming pool.
how would you find the mass of 250 mL of water
Why would the mass change? The sugar molecules are still there, only now they are surrounded by water molecules, so the "dissolve". Matter (mass) cannot be destroyed, nor can it be created, so the mass of the solution will be equal to the mass of the sugar + the mass of the water.
It depends on the size of the mass: a swimming pool will have a greater mass and hold more gallons than a kitchen sink.
okk first find like a tube thingy and find the mass of it on the balance and write it down somewhere then put the water in the tubee and find the mass and write it downn when your donee subtract the mass of the tube from the mass of the tube with water in it and your answerr is the mass of the water ***make sure the tube has no water in it or ANYTHING because it could change the mass okk first find like a tube thingy and find the mass of it on the balance and write it down somewhere then put the water in the tubee and find the mass and write it downn when your donee subtract the mass of the tube from the mass of the tube with water in it and your answerr is the mass of the water ***make sure the tube has no water in it or ANYTHING because it could change the mass
Find the mass of an empty container using a balance. Fill the container with 100 ml of water and measure the mass again, The difference between the two measurements is the mass of 100 ml of water.
By definition, it weighs 50 grams. A litre of water weighs a kilogram.
You can weigh it; or you can calculate it based on the known density of water.
you get a container and the amount of water you need and a whatever your going to use to measure the mass. first you find the mass of the container then you put the water in the cup and find the mass then subtract the mass of the cup from the mass of the cup and water then there's your answer.
Firstly, weigh the empty cup. Then weigh the cup with the water and subtract the mass of the cup.
1. Find the molar mass of the hydrate.Find the molar mass of the water molecules (18.01528 x # water molecules) and of the anhydrate; add the values together to find the molar mass of the hydrate.Molar Mass Water + Molar Mass Anhydrate = Molar Mass Hydrate2. Find the percent of water in hydrate.Divide the molar mass of water by the molar mass of hydrate; multiply by 100%.- Mass waterMass hydrate x 100%
Multiply moles by molecular mass of water (18), gives you 223.8g. Remember this formula: Number of moles = mass / molecular mass
Weigh the water while in the beaker. Empty the water and weight the empty beaker. Subtract the 2nd weight from your original weight, and you'll have the mass of the water.
You would determine its mass using a mass balance.
The typical density of water is around 1g/cm3. Thus, a 300ml sample of water would weigh about 300g. In order to find the exact mass, one would need to know the temperature of the sample and use water's density at that temperature in the calculation mass times density equals volume.
u2/cm/g3 * * * * * I have no idea about the above answer, but it does not appear to answer the question. The best way to find the mass of a given quantity of water is to use a balance to find the mass of an empty container. Then pour the water into the container and measure their combined mass. The difference between the two is the mass of the water.
Mass of a pony
Mass = density x volume
you drop the coin into water and find volume then weigh it to find mass if the volume is greater than mass it will float.
Immerse it in water and measure the displacement. Then calculate the mass of the amount of water displaced.
You don't. You weigh it to get the mass. The displaced water is to find the volume, after which you can calculate the density.
You would need to know the density (e.g. mass per unit of volume) of the water. There are charts for this, but water temperature is a variable that must be considered. It's discussed on Wikipedia in the Water (molecule) article.
percent water= (mass of water lost/ mass of hydrate) x 100
Assuming that it is a half litre bottle of water, the water would have a mass of 500g so the bottle would have a mass of 95g. However it might be a pint bottle of water, in which case the water would have a mass of 568g, leaving the bottle with a mass of 27g.
You would find that the water would dissolve the sugar cube before you could get a measurement for its water displacement. A better way to get its volume would be to get its mass, then look up the density for sucrose (table sugar), then apply the equation V=M/D (volume, mass, density) and solve.
