Final answer:
To determine the number of moles in 578g of water, divide the given mass by the molar mass of water (H₂O), resulting in 32.072 moles.
Explanation:
To find the number of moles in 578g of water, we first need to calculate the molar mass of water (H₂O), which is 18.02 g/mol. Next, divide the given mass by the molar mass:
578g ÷ 18.02 g/mol = 32.072 moles.
Therefore, there are 32.072 moles of water in 578g of water.
