Question 1 of 10 What would you need to do to calculate the molality of 10 mol of NaCl in 200
mol of water?
A. Convert the 200 mol of water to kilograms of water.
B. Convert the 200 mol of water to liters of water.
C. Convert the 10 mol of NaCl to grams of NaCl.
O D. Convert the 10 mol of NaCl to kilograms of NaCl.
SUBMIT

A. Convert the 200 mol of water to kilograms of water.

Molality (m) shows the number of moles dissolved in every 1000 grams(1 kg) of solvent.

m = Molality

n = number of moles of solute

p = Solvent mass (gram)

or

solute = 10 mol NaCl

solvent = 200 mol water⇒Convert to kilograms of water.
