Question

Formula of Molarity (in ml) is .................. $\times 100/v$

• A. $Weight÷GramMolecularWeight$
• B. Weight + Gram Molecular Weight
• C. $Weight\times GramMolecularWeight$
• D. None of these

Answer 1

Answer: (A)

$Weight÷GramMolecularWeight$

Molarity$=\frac{no.ofmoles}{volume}$

Molarity(in ml)$=no.ofmoles\times \frac{100}{v}$

No. of moles$=\frac{weight}{grammolecularweight}$

$\Rightarrow$Formula of molarity$=\left(\frac{weight}{grammolecularweight}\right)\times \frac{100}{v}$
