Question

A sample of CaNO3 weighing 0.83g is placed in a 10ml volumetric flask.The flask is then filled with water to the mark.Calculate molarity of the solution

Answer 1

Answer:

Explanation:

mass= 0.83

Volume=10ml

Molarity=

Molar mass of given compound=102g

Molarity=no of moles/volume of solutio in litres

0.83/10200×10/1000

=.21M
