Answer

Explanation:

Step1: Identify the molarity values

Molarity is a measure of concentration. We just need to compare the molarity (M) values of each solution. The molarity values are:

  • For $H_2SO_4$: $10\ M$
  • For $PbSO_4$: $1.0\ M$
  • For $H_2O_2$: $10.5\ M$
  • For $NaCl$: $10\ M$

Step2: Compare the molarity values

We compare the values $10$, $1.0$, $10.5$ and $10$. Since $10.5>10 > 1.0$, the $H_2O_2$ solution has the highest molarity.

Answer:

$2.0\ mL$ of $10.5\ M\ H_2O_2$, where $H_2O_2$ has a molar mass of $34\ g/mol$
