Answer:
The system has 35% of B.
Explanation:
Number of A atoms = 65
Number of B atoms = 35
Mass of atom A = M
Mass of atom B = 18M
Total atoms of the system = 65 + 35= 100
Total of atoms of B = 35
The percentage of B is the system ;
The system has 35% of B.

Hello!
In this case, since the molarity of magnesium chloride (molar mass = 95.211 g/mol) is 1.672 mol/L and we know the density of the solution, we can first compute the concentration in g/L as shown below:
Next, since the density of the solution is 1.137 g/mL, we can compute the concentration in g/g as shown below:
Which is also the by-mass fraction and in percent it turns out:
