Question

Calculate. The molairy of solution containing in 45g
of glucose in 250cmcube of solution
​

Answer 1

Answer: 1M

Formula used:  $MOLARITY=\frac{MASS(Solute)}{MOLAR MASS} *\frac{1000}{VOLUME}(ml)$

Explanation:

Given,

Mass(solute)=45 g

Volume= 250 cm³

Molar mass of Glucose (C₆H₁₂O₆)

6×12+12×1+6×16

= 180 u.

Using formula of Molarity we get,

$\frac{45}{180}* \frac{1000}{250}$

$=0.25*4\\=1M$
