Consider the reaction cacn2 + 3 h2o → caco3 + 2 nh3. how much nh3 is produced if 187 g of caco3 are produced? 1. 2.13 mol 2. 63.6 mol 3. 3.74 mol 4. 36.1 mol 5. 1.06 mol 6. 72.3 mol

Equation is as follow,

CaCN ₂ + 3 H ₂ O → CaCO ₂ + 2 NH ₃

According to this equation,

When,

100 g CaCO₃ (1 mole) is produced when = 34 g NH₃ (2 moles) is produced

So,

187 g CaCO₃ will be produced then = X g of NH₃ will produce

Solving for X,

X = (187 g * 34 g) : 100 g

X = 63.58 g of NH₃ will be produced

Result:

Option-2 is correct answer.
