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
