How many moles of strontium chloride are included in 20 ml of 0.2 m strontium
chloride?

Number of moles of strontium chloride = 0.004 mol

Explanation:

Given data:

Molarity = 0.2 M

Volume = 20 mL

Moles of strontium chloride = ?

Solution;

Formula:

Molarity = number of moles of solute / volume in litter

Now we will convert the volume into litter.

20 mL/1000mL × 1 L

0.02 L

Now we will put the values in formula:

Molarity = number of moles of solute / volume in litter

Number of moles of solute = Molarity × volume in litter

Number of moles of solute = 0.2 mol/L × 0.02 L

Number of moles of solute = 0.004 mol
