Answer 1

For your information, I usually don't answer questions if someone asks too many at once. This is not a Homework or Test Answering Service. This question is very basic and should be just chemistry as the header.

In order to find the formula mass of BaSO₄ you need to add M_Ba + M_S + 4M_O where Ms are the molar masses off of the periodic table. This will be the grams/mole which is the grams for 1 mole.
