Question

4.5 grams of a substance [molar mass=90g/mol] is dissolved in 250ml solution,then molarity of solution is

No wrong answer please

Answer 1

Answer:

0.2M/0.2 Molarity

Explanation:

Molarity,M = weight of Solute * 1000/Gram molecular Mass of solute * Volume of solvent.

=> M = 4.5*1000/90*250

=> 4.5*4/90

=> 0.2 M

Refer attachment mate :)

Answer 2

M = 4.5 x 1000/90 x 250

=> 0.2 M
