Calculate the molar mass of ammonium carbonate. a. 88.05 g/mol b. 78.05 g/mol c. 96.09 g/mol d. 112.09 g/mol e. none of the above

Explanation:

The molar mass of ammonia carbonate

(NH4)2. C03

The atomic weight of Nitrogen is 14.01g/mol

The atomic weight of Hydrogen is 1.008g/mol

The atomic weight of Carbon is 12.01g/mol

The atomic weight of Oxygen is 16g/mol

2(14.01 +1.008x4)+ 12.01+ 16.0 × 3

2(14.01 + 4.032) + 12.01 + 48

2(18.042) + 60.01

36.084 + 60.01 = 96.09g/mol = c

The molar mass of ammoniuncarbonate is 96.09 g/mol (Option C)

Explanation:

Step 1: Data given

ammonium carbonate = (NH4)2CO3

Molar mass of N = 14 g/mol

Molar mass of H = 1.01 g/mo

Molar mass of C = 12 g/mol

Molar mass of 0 = 16 g/mol

Step 2: Calculate molar mass of (NH4)2CO3

We have 2x N = 2*14 g/mol = 28 g/mol

We have 8x H = 8*1.01 g/mol = 8.08 g/mol

We have 1x C = 12.01 g/mol

We have 3x O = 3* 16 g/mol = 48 g/mol

Molar mass of (NH4)2CO3 = 28 + 8.08 + 12.01 + 48 = 96.09 g/mol

The molar mass of ammoniuncarbonate is 96.09 g/mol (Option C)
