m = moles/kg solvent
5.3 = moles/0.125
solve for moles.
Then moles = g/molar mass.
Solve for molar mass.
What is the molar mass of a solute if 62 g of the solute in 125 g of water produce a 5.3 molal solution?

given
m= 5.3, given mass= 62, molar mass= find?, weight= 125
m=given mass/molar mass ×
weight
when weight is in g then change it into kg.
then,
5.3= 62×1000/125×53
Now calculate,
m= 5.3, given mass= 62, molar mass= find?, weight= 125
m=given mass/molar mass ×
weight
when weight is in g then change it into kg.
then,
5.3= 62×1000/125×53
Now calculate,
