Question

A solution containing 80.0 grams of glucose (C₆H₁₂O₆) is dissolved in enough water to make 250 mL of solution. What is its molarity?

Answer 1

Molar mass of glucose = 180.156 

Moles of glucose $=\frac{80}{180.156}=0.444moles$

Volumes = $\frac{250}{1000}=0.25$

$Molarity=\frac{0.25}{0.444}=0.56M$
