MCQ
Calculate .......$M$ Molarity of a $63 \%$ $w/w\,HNO_{3}$ solution if density is $5.4 $ $g / mL$
- ✓$54$
- B$12$
- C$10$
- D$8$
✓
Answer
Correct option: A.
$54$
a
$M =\frac{\% W , W \times d \times 10}{ M _{\text {solute }}}=\frac{63 \times 5.4 \times 10}{63}=54$
$M =\frac{\% W , W \times d \times 10}{ M _{\text {solute }}}=\frac{63 \times 5.4 \times 10}{63}=54$
