How many moles of C6H10S are in 225 grams?
To find the number of moles, you need to first calculate the molar mass of C6H10S: Carbon has a molar mass of 12.01 g/mol, hydrogen has a molar mass of 1.01 g/mol, and sulfur has a molar mass of 32.07 g/mol. Adding these up gives a molar mass of 114.17 g/mol for C6H10S. Then, divide the given mass by the molar mass to find the number of moles: 225 g / 114.17 g/mol ≈ 1.97 moles.

A solution was prepared by dissolving 40.0 g of KCl in 225 g of water. Calculate the mole fraction of KCl in the solution?
First, calculate the moles of KCl: 40.0 g / 74.55 g/mol = 0.536 mol. Then calculate the moles of water: 225 g / 18.015 g/mol = 12.49 mol. The total moles of solute and solvent is 0.536 + 12.49 = 13.03 mol. Finally, calculate the mole fraction of KCl: 0.536 mol / 13.03 mol = 0.041.
