Question

solution contain 16g of methanol and 90g of water mole fraction of methanol is​

Answer 1

Answer:

Explanation:

moles of solute = 16 g / 32 g / mole = 0.50 moles  

moles of solvent = 90.0 g / 18 g / mol = 5.0 moles  

total number of moles of solute + solvent = 5.50 moles  

mole fraction of the methanol = 0.50 / 5.50 = 0.1
