Molarity is defined as

A

the number of moles of solute dissolved in `1 dm^(3)` of the solution

B

the number of moles of solute dissolved in 1 kg of solvent

C

the number of moles of solute dissolved in `1 dm^(3)` of the solvent

D

the number of moles of solute dissolved in 100 mL of the solvent

Text Solution

Verified by Experts

The correct Answer is:
A
We have the defineition for molarity as the number of moles of solute present in one litre of the solution
`therefore` molarity (M)=`("Number of moles of solute")/("Volume of solution" (in L))`
