Question

Which of the following combinations of information would allow you to calculate concentration in grams per liter? Check all that apply.
a.moles of solute and mass of solution
b.moles of solute, mass of solution, and density of solution
c.mass of solute and volume of solution
d.mass of solute and mass of solvent

Answer 1

Answer:

c.mass of solute and volume of solution

Explanation:

Given that:-

The concentration has to be calculated in grams per litre.

Grams per litre means that 1 gram of the solute present in 1 L of the solution. Thus, the expression for the calculation of the concentration in g/L is:-

$C(g/L)=\frac{Mass_{solute}}{Volume_{Solution}}$

Thus, the combination of the information we need to calculate the same is:-

c.mass of solute and volume of solution
