Question

What is the molarity of a 50.0 mL solution that contains 0.65 moles of
Sodium sulfate?

Answer 1

• Volume=50mL=0.050L

• Moles=0.65mol

$\\ \sf\longrightarrow Molarity=\dfrac{Moles\:of\:solute}{Volume\:of\: solution\:in\:L}$

$\\ \sf\longrightarrow Molarity=\dfrac{0.65}{0.05}$

$\\ \sf\longrightarrow Molarity=0.13M$
