Question

The molarity of a 15 % of NaCl solution in water is

Answer 1

I think it should be 0.15

Answer 2

Hey dear,

● Answer -
Molality = 2.5641 mol/kg

● Explaination -
# Given -
W2/W2 = 15% = 0.15

# Solution -
Molality of solution is calculated by -
Molality = Moles of solute / mass of solvent
Molality = (W2/M2) / W1
Molality = (W2/W1) / M2
Molality = 0.15 / (58.5×10^-3)
Molality = 2.5641 mol/kg

Therefore, molality of 15% NaCl solution is 2.5641 mol/kg.
