Hey could you guys tell me whether I am on the right track with this or not. First Problem: A tablespoon of sugar, [tex]C_1_2H_2_2O_1_1[/tex], weighs 2.85g. A.) How many moles of sugar are there in a tablespoon? Do I calculate the molar mass of sugar in grams and then divide 2.85g by the molar mass? To give me the moles? Also, if I were to calculate how many grams of O there are in 2.85g of sugar would I just multiply the number of moles in 2.85g of sugar by the molar mass of oxygen times the number of oxygen atoms? Second Problem: Sample A is [tex]1.555~x~10^{-5}[/tex] mole of [tex]AlK (SO_4)_2~12H_2O[/tex] A.) How many grams of O are present? Do I start by multipliying [tex]1.555~x~10^{-5}[/tex] by the molar mass of [tex]AlK (SO_4)_2~12H_2O[/tex]?? Thanks
