Q12

**Question 12:** The Molarity of 2.7 N H₃PO₄ is 

- (a) 8.1 
- (b) 0.9 
- (c) 7.1 
- (d) n/a

**Options:**

- ○ d
- ○ c
- ○ a
- ○ b

This question involves calculating the molarity of a phosphoric acid solution when given the normality. The options provided suggest different possible molarity values. The correct answer should be selected based on the formula that links molarity (M) to normality (N): 

\[ M = \frac{N}{n} \]

where \( n \) is the number of hydrogen ions that the acid can donate per molecule.
