Question

What is the volume of a 0.5 M solution of HCl if it contains 36.5 grams of solute?

Molar mass (H -1 g/mol)(Cl - 35.5 g/mol)

___ L (Answer Format: X)

Answer 1

Answer: 2 L or 2000 mL

Step-by-step explanation:

A 1 molar (1 M) solution is equal to 1 mole of the solute dissolved in 1 L of solution.

For HCl (mw 36.5) 1 mole = 36.5 g

1 molar (1 M) = 1 mole/1 liter (or 36.5 g/L)

So

0,5 M = 1 mole/x

(x is the volume we are solving for)

Multiply both sides by x and you get

0.5x=1

Now multiple both sides by 2

X=2

So it’s 2L volume
