A person drinks 1.50 × 103 g of water, H2O, per day. How many moles is this?
6. How many grams of CH3OH are in 0.42 mol CH3OH?
To find the number of moles in 1.50 × 10^3 g of water, we need to use the molar mass of water, which is 18.015 g/mol.
Number of moles = Mass of water / Molar mass of water
Number of moles = 1.50 × 10^3 g / 18.015 g/mol
Calculating this, we get:
Number of moles = 83.264 moles
Therefore, there are 83.264 moles of water in 1.50 × 10^3 g of water.
To find the number of grams in 0.42 mol of CH3OH, we need to use the molar mass of CH3OH, which is 32.04 g/mol.
Mass of CH3OH = Number of moles * Molar mass of CH3OH
Mass of CH3OH = 0.42 mol * 32.04 g/mol
Calculating this, we get:
Mass of CH3OH = 13.49 g
Therefore, there are 13.49 grams of CH3OH in 0.42 mol of CH3OH.
