How many grams of calcium

160.32 g of Ca

Explanation:

The reaction is this:

Ca + 2HCl → CaCl₂  +  H₂

Mass of produced H₂: 8 g

If we convert the mass to moles → 8 g . 1mol/2g = 4 mol

So ratio is 1:1. Therefore 4 moles of H₂ were produced by 4 moles of Ca.

Let's convert the moles to mass → 4 mol . 40.08 g/1mol = 160.32 g
