Question

What is true of a solution of 1.0 M HCl(aq)? It contains 1.0 gram of HCl per 100 grams of water. It contains 1.0 gram of HCl per 1 liter of solution. It contains 1.0 mole of HCl per 100 milliliters of water. It contains 1.0 mole of HCl per 1 liter of solution.

Answer 1

Answer: It contains 1.0 mole of HCl per 1 liter of solution.

Explanation:

Molarity : It is defined as the number of moles of solute present in one liter of solution.

Formula used :

$Molarity=\frac{n}{V_s}$

where,

n =  moles of solute

$V_s$ = volume of solution in liter

$1.0M=\frac{1mole}{1L}$

Thus 1.0 M solution means the solution contain 1 mole in 1 liter of solution.

Answer 2

Answer:

D) It contains 1.0 mole of HCl per 1 liter of solution.
