What is the molar concentration of Na in a solution prepared by dissolving 100.0g of Na3PO4 in sufficient H2O to form 2.00 L of solution?
The molarity of that solution is 0.82, based on sodium phosphate's molar mass and the given volume of solution. Since there are three sodium ions for every one formula unit of sodium phosphate, the molar concentration of Na+ ions is 0.82(3)=2.46.
How do ear gauge piercings work and the I'm confused about the sizings?
Starting with a normal ear piercing size (piercing gun stud) The first one listed is normal size and go up in size from there. 14g = 1.6mm 12g = 2.0mm 10g = 2.4mm 08g = 3.2mm 06g = 4.0mm 04g = 5.0mm 02g = 6.0mm 01g = 7.0mm 0g = 8.0mm 00g = 10.0mm 0g and 00g are the largest the average person wants to go to unless they don't care about the ear lobe shrinking down to a normal size down the road. Over )) the sizes would go up by millimeters or imperial fractional sizes. The lower the gauge number the thicker the jewellery.
How much carbon dioxide can one soda have?
I can say for a fact that there is alot more than 2.2g CO2/Liter I took an unopened Coke and weighed it and then I opened it up, closed it and shook it multiple times until there was no more buildup of pressure. I then let it sit for a few days repeating when I noticed the bottle was getting pressurized. This was also done with the bottle at room temperature where the CO2 will be released the quickeset without causing the liquids to evaporate. At the end of this I weighed the bottle again and found it lost 4.42g. This was a .591mL plastic soda bottle. This is equivilant to 7.48g of CO2/Liter of Coka Cola So to sum it up: In 1 Liter of Coka Cola there is 7.48g of CO2, could be a little more if I let it sit even longer, but it is negligable at that point, only maybe .02g more. Keep in mind that various types of sodas will be differant as some soda is more carbonated than others.
