Final answer:
To find the mass of water from the given number of moles (4.67 mol), we use the molar mass of water (18.015 g/mol) and multiply the two, resulting in 84.11 grams of water.
Step-by-step explanation:
To determine how many grams of water (H2O) are in 4.67 mol of the compound, we use the molar mass of water as a conversion factor. The molar mass of water is calculated by adding the atomic masses of hydrogen (2 x 1.008 g/mol) and oxygen (15.999 g/mol), which gives us approximately 18.015 g/mol for the molar mass of water. To perform the conversion, we multiply the number of moles by the molar mass:
4.67 mol H2O × 18.015 g/mol H2O = 84.11 g H2O
Therefore, 4.67 mol of water is equivalent to 84.11 grams.
