Question

C. CaCl2 can be melted to produce calcium metal and give off chlorine gas. The equation for this

is CaCl2()→ Ca(s) + Cl2(g). If 277.45 g CaCl2 were melted, how many grams of Ca(s) would
be formed? (10 points)

HELP MEEEEE PLEASE

Answer 1

Total gram of Ca = 99.26 g

Step-by-step explanation:

Given:

Mass of CaCl₂ = 277.45 g

Find:

Mass of Ca

Computation:

Ca = 40 g/mol

Cl₂ = 2 (35.5) g/mol = 71 g/mol

Total CaCl₂ = 111 g/mol

Total gram of Ca = [40 / 111] 277.45 g

Total gram of Ca = 99.26 g
