Note: moles to grams, or grams to moles you will need to use molar mass (g/mol).1)how many moles are in 20.2 g hcl? 2) how many grams are in 2 moles of hcl? note: when converting from moles to molecules, you need the following: 1 mole = 6.022 x 1023 molecules 3) how many molecules are in 23 moles of sodium? 4) how many moles are in 8.022 x 1026 molecules of nacl? note: 1 mole = 22.4 l 5) how many moles are in 5 liters of h2 gas? 6) how many liters are in 5 moles of h2 gas? multiple conversions in one problem. 7) how many grams of hcl will be produced with 16.2 grams of h2 and excess cl2? (h2 + cl2 -> 2hcl) 8) how many liters are there in 46 g of cl2 gas?
