3) What is the molecular weight of water?

18g/mol 20g/mol 17g/mol 16g/mol

Correct Answer: 18g/mol

Explanation:

The molecular weight of water (H2O) is approximately 18.015 g/mol (grams per mole). This is the sum of the atomic weights of two hydrogen atoms (1.008 g/mol each) and one oxygen atom (16.00 g/mol).

4) What is the unit of molecular weight?

g/mol gm/l gram kilogram

Correct Answer: g/mol

5) Which solution the solute concentration is lower?

Saturated solution Unsaturated solution Super saturated solution Normal solution

Correct Answer: Super saturated solution
