A student makes a solution containing 125g of acetonitrile (CH₃CN)and 300g of water.What is the mol fraction of acetonitrole? A) 0.845 B) 0.155 C) 0.294 D) 0.706 E) 0.0453

Question

Quizplus · Accepted Answer

The mole fraction is calculated by dividing the moles of acetonitrile by the total moles of the solution. Moles of acetonitrile = 125g / 41.05 g/mol = 3.045 moles. Moles of water = 300g / 18.015 g/mol = 16.65 moles. Mole fraction of acetonitrile = 3.045 / (3.045 + 16.65) = 0.155.
