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.
you need to know the volume of water. When the pool is first filled, if you look at the water meter before and after you can know the volume. Or, there are ways to approximate it based on its shape. Then you multiply that by 8.35 lbs per gallon.
Determine the cubic footage of the pool interior (Length X Width X Depth) and multiply that by 7.5, which is the approximate number of gallons per cubic foot.

how would you find the mass of 250 mL of 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
You can weigh it; or you can calculate it based on the known density of water.
Multiply moles by molecular mass of water (18), gives you 223.8g. Remember this formula: Number of moles = mass / molecular 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.
Mass = density x volume
You would determine its mass using a mass balance.
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.
Mass of a pony
To find the mass of an object based on the displaced water, you can make use of Archimedes' principle. Measure the volume of the water displaced by the object, and then multiply it by the density of water (usually 1 g/mL). This will give you the mass of the object.
density = mass/volume Determine the mass and volume of the water, and then divide the mass by the volume, and that will give you the density.
