1. The problem statement, all variables and given/known data

BaCl2+ 2NaF -->BaF2 + 2NaCl

2. Relevant equations

See above...how to get 100g of the BaF2 product?

3. The attempt at a solution
Did molecular weight of each compound in moles/g

Found MW for BaF2 as 173.31
Then took 100g/173.31 to get 0.57 moles. Did MW for other compounds now not sure where to go from here?

Have you read the linked page?

How many moles of BaCl2 needed to produce 0.57 moles of BaF2?

How many moles of NaF needed to produce 0.57 moles of BaF2?

Need 1.14moles to produce 0.57 moles BaF2
Need 0.57 BaCl2 moles to produce 0.57 moles BaF2
So I need 47.89g of NaF
And 118.77g of BaCl2
Is that right?
