Calculate the molality of a 150% by mass solution of mgcl, fw-95.3 g/mol in h. o. the density of tis solution is 1.127 gim 0.0134 m 0.157 m 1.58 m 1.86 m 11.8 m igator delete backspace u 10 pilli

1.86 m

Explanation:

Molality of a solution is defined as the number of moles of solute dissolved per kg of the solvent.

where,

n = moles of solute

= weight of solvent in g

Given : 15.0 grams of is present in 100 g of solution

Moles of solute

mass of solution = 100 g

density of solution = 1.127g/ml

mass of solvent = mass of solution - mass of solute = 100 g - 15.0g = 85.0 g

Thus molality of a 15.0% by mass solution of is 1.86m.
