Answer:
Calculate moles KCl: 2.55 g / 74.55 g/mol = 0.0342 moles KCl
Volume KCl = 0.0342 mol X (1 L/0.150 mol) = 0.228 L X 1000 mL/L = 228 mL
Explanation:
Volume=288mL
Given:
Molarity=0.140 M
Mass=2.65 g
To find:
Volume=?
Molar mass of KCl = 74.55 g/mol
Firstly, we need to calculate the number of moles of KCl:
[tex]\text{Number of moles}=\frac{\text{Given mass}}{\text{Molar mass}} \\\\\text{Number of moles}=\frac{2.65g}{74.55g/mol} \\\\\text{Number of moles}=0.0355 moles[/tex]
In order to calculate the volume,
[tex]\text{ Volume of KCl} = 0.0342 mol * (1 L/0.150 mol) \\\\\text{ Volume of KCl} = 0.228 L * 1000 mL/L \\\\\text{ Volume of KCl} = 228 mL[/tex]
The volume in mL will be 228mL.
