<em>Answer:</em>
- The option C is correct.
- CH4N, 90g, C3H12N3.
<em>Explanation:</em>
<em>Option C:</em>
- The molecular formula is C3H12N3.
- If we take ratio 3:12:3 that will be equal to 1:4:1 so its empirical formula will be CH4N.
- The molar mass of molecular formula = (12×3) + (1×12) +( 14×3) = 98 g
<em>Option A :</em>
- In option A , molecular and empirical formula are both correct but molar mass is not valid. It should be 169 acc. to molecular formula.
<em>Option B:</em>
- In option B, molecular formual is not valid.
- It should be as C6H16O2
