In the wintertime, you decide to buy a helium balloon at Dollar Tree. It is fully inflated in the store. However, when you walk outside in the cold, the balloon
deflates quite a bit. So, you go back into the store, to exchange it for a different
balloon. But once you walk back into the warm store, the balloon is fully inflated!
Why does the balloon deflate outside in the cold winter weather and inflate inside
the warm store? Which gas law, (Charles, Boyle, Guy-Lussacs law) causes this to
happen?

Calculate the number of molecules present in 0.750 mol of mgo.

Ican determine the molar mass of an element by looking on the under the atomic mass for the element. for example the molar mass of phosphorus is 30.974 grams/mole. avogadro’s number tells me the amount of representative particles in 1 mole of any substance. this means 12.011 gram sample of carbon and a 32.0 gram sample of sulfur have the same number of atoms.

Gusing the milligrams of ascorbic acid you entered above, the ratio of total sample volume to aliquot volume, and the total milligrams of the vitamin c tablet that you dissolved, calculate the mass of ascorbic acid in the vitamin c tablet for each trial. do this by scaling up to find the amount (mg) of ascorbic acid in your 250 ml flask. enter your calculated mass of ascorbic acid in the vitamin c tablet, for each trial. be sure to enter your calculated mass in the corresponding order that you entered your milligrams of ascorbic acid. the milligrams of ascorbic acid you entered for entry #1 previously should correspond to the mass of ascorbic acid that you enter for entry #1 here.
