Answer:

1. 98.086 g/mol

2. 18.042 g/mol

3. 58.321 g/mol

Explanation:

Molar mass is the mass measured in grams of 1 mole of a substance. It is obtained by the formula;

Relative Atomic mass * Molar mass constant(1g/mol)

Therefore, molar mass for;

1. Sulfuric Acid

= (1.008 *2) + (32.07 * 1) + (16.00 * 4)

=  2.016 + 32.07 + 64

= 98.086 g/mol

2. Ammonia

= (14.01 *1) + (1.008 * 4)

= 14.01 + 4.032

= 18.042 g/mol

3. Magnesium Hydroxide

= (24.305 *1) + (16.00*2) + (1.008*2)

= 24.305  + 32.00 + 2.016

= 58.321 g/mol
