What is the molarity of a solution of 10% by mass cadmium sulfate, CdSO4 (molar mass = 208.46 g/mol) by mass? The density of the solution is 1.10 g/mL. a) 0.528 M
b) 0.436 M
c) 0.479 M
d) 0.048 M
e) 22.9 M

a. 0.528 M ..

Explanation:

Hello!

In this case, since the given by-mass percent can be written as:

By using the density and molar mass of the solute, cadmium sulfate, we can compute the molarity, by also making sure we convert from mL to L of solution:  

Thereby, the answer is a. 0.528 M .

Best regards.

the correct option is c.

isotopes refers to different forms of the same element with the same atomic number but different mass number as a result of difference in their neutron numbers. isotopes have different relative atomic mass but share the same chemical properties.
