Question

question 2. which of the following represents the mass of one mole of water (h₂o)? 2.02 grams 16.00 grams 18.02 grams 20.02 grams

Explanation:

Step1: Find atomic masses

Atomic mass of H = 1.01 g/mol, O = 16.00 g/mol

Step2: Calculate molar mass of $H_2O$

$\text{Molar mass} = (2 \times 1.01) + 16.00$

Step3: Compute the total

$\text{Molar mass} = 2.02 + 16.00 = 18.02$ g/mol

Answer:

18.02 grams
