Question

Converting moles to mass in grams using dimensional analysis

1. 0.0728 mol to Silicon

2. 5.5mol of H2O

3) 0.0728 of Ca(H2PO4)2

Answer 1

Step-by-step explanation:

1) 0.0728 x (28.086 g Si/ 1mole Si) =2.04 g Si

2) 5.5 mol H20 x (18g H20/1mole H20) = 99 g H2O

3) 0.0728 moles Ca(H2PO4)2 x ( 234 g/ 1mole) = 17.04 g Ca(H2PO4)2
