Short Answer

Expert verified

500 grams of water contain about $1.67 \times 10^{25}$ molecules.

Step by step solution

Step 1. Write down the given information.

One gram of water contains $3.34 \times 10^{22}$ molecules.

Step 2. Evaluating molecules in 500 grams of water.

The molecules in 500 grams of water are evaluated as: $500 \times 3.34 \times 10^{22}$ .

Therefore, evaluating product,

$\begin{matrix} 500 \times 3.34 \times 10^{22} = 5 \times 10^{2} \times 3.34 \times 10^{22} \\ = 1.67 \times 10^{25} molecules. \end{matrix}$

Step 3. Conclusion.

500 grams of water contain about $1.67 \times 10^{25}$ molecules.
