36.5g of hcl are dissolved in 180g of h2o. what is the mole fraction of the solute
Answered by bonjo
the solute is the HCl because it dissolved in water (a solvent). we have the mass so we can calculate the mole using m/Mr.

the mole of water is also m/Mr

the mole fraction is the mole of the solute divided by the total mole of the solution.

SO LIKE 36.5g/(180/18)=3.65?
Answered by bonjo
calculate the mole of HCl using m/Mr

calculate the mole for water using the same formula

add to two moles to get the total mole of the solution.

divide the mole of HCl by the total mole to get your mole fraction.
