Answer 2

Given Information:

- Number of water molecules (H2O): N(H2O) = 3.6 × 10^24

To find:

- Mass of water (m)

Solution:

The given information provides the number of water molecules. To find the mass of water, we need to multiply the number of molecules by the molar mass of water (M).

The molar mass of water (H2O) is the sum of the atomic masses of its constituent atoms. The atomic masses are as follows: - Atomic mass of hydrogen (H): 1.00784 g/mol - Atomic mass of oxygen (O): 15.999 g/mol

To calculate the molar mass of water (H2O): M(H2O) = 2 × M(H) + M(O)

Substituting the atomic masses: M(H2O) = 2 × 1.00784 g/mol + 15.999 g/mol

Calculating the molar mass of water: M(H2O) = 18.01528 g/mol

Now, we can find the mass of water (m) using the formula: m = N(H2O) × M(H2O)

Substituting the given values: m = (3.6 × 10^24) × (18.01528 g/mol)

Calculating the mass of water: m ≈ 6.4844064 × 10^25 g

Therefore, the mass of water is approximately 6.4844064 × 10^25 grams.
