Question

The molality of a solution containing 8.1 moles of solute in 4,847 g of solvent is _____. 1.7m 598m 39m 0.17m

Answer 1

when molality = no.of moles of solute/weight Kg of solvent

and when we have the no. of moles of solute = 8.1 moles
and the weight Kg of the solvent =4847 g /1000 = 4.847 Kg
so by substitution :
Molarity = 8.1m / 4.847Kg = 1.67 M

Answer 2

Answer:

1.7m
