The molarity of

{HNO}_{3}

in a sample which has density

1.4g / mL

and mass percentage of

63%

is ________ (Molecular Weight of

{HNO}_{3} = 63

)

Correct answer

0

Step-by-step solution

63%\dfrac{w}{w} ⟶ HN{O}_{3}

solution

M = \dfrac{63 \times 1.4}{63 \times 100} \times 1000mole / L

M = 14mole / L
