Molar mass
CaH₂ = 42.0 g/mol
H₂ = 2.0 g/mol
<span>Balanced chemical equation :
</span>CaH2 + 2 H₂O = Ca(OH)₂ + 2 H₂
42.0 g CaH₂ --------------------- 4.0 g H2
? g CaH₂ ---------------------- 4.550 g H2
mass = 4.550 * 42.0 / 4
mass = 191,1 / 4
mass =<span> 47.775 g of CaH₂</span>
<span>hope this helps!</span>
