How many moles of ammonium carbonate are needed to decompose in order to produce 6.52g of carbon dioxide? Ammonium oxide is the other product.

A.) 0.116 moles

B.) 0.251 moles

C.) 0.148 moles

D.) 286.88 moles

Help me solve please...

Option (C) is correct.

Explanation:

Decomposition reaction:

Molar mass of = 44.01 g/mol

No. of moles = (mass)/(molar mass)

So, 6.52 g of = moles of = 0.148 moles of

According to balanced equation-

1 mol of is produced from decomposition of 1 mol of

So, 0.148 mol of is produced from decomposition of 0.148 mol of

Hence, option (C) is correct.

the law of conservation of mass states that in a chemical reaction, the total mass of reactants is equal to the total mass of products. because atoms are only rearranged in a chemical reaction, there must be the same number of sodium atoms and chlorine atoms in both the reactants and products
