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

Answer»

ANSWER: 1M

FORMULA used:  MOLARITY=\frac{MASS(<klux>SOLUTE</klux>)}{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
