Cadmium bromide is used in photography and lithography. what is the molality of a solution prepared by dissolving 45.38 g of cdbr2 in 375.0 g of water?

Given:

As we know the formula,

→

By substituting the values, we get

hence,

The molality will be:

=

=

Thus the above answer is right.

0.44 m is the molality

Explanation:

Molality means mol of solute in 1kg of solvent.

Solute → CdBr₂

Solvent → H₂O

Mass / Molar mass = 45.38 g / 272.21 g/m = 0.167 moles

1 g = 1x10⁻³ kg

375 g = 0.375 kg

0.167 m/0.375 kg = 0.44 m

if you mean hydrogen and oxygen then water is the product
