JEE Main 2025 — 3 April, Morning Shift — Question 16

During estimation of nitrogen by Dumas' method of compound X (0.42 g)

$\_\_\_\_\_$ mL of $\mathrm{N}_{2}$ gas will be liberated at STP. (nearest integer)

(Given molar mass in $\mathrm{g} \mathrm{mol}^{-1}: \mathrm{C}: 12, \mathrm{H}: 1, \mathrm{~N}: 14$ )

Numerical answer — enter this value.

Formula of compound $=\mathrm{C}_{4} \mathrm{H}_{10} \mathrm{~N}_{2}$

= 86

Moles of compound $=0.00488$

Moles of $\mathrm{N}_{2}=0.00488$

Volume of $\mathrm{N}_{2}=0.1093 \mathrm{~L}$

$=109.3 \mathrm{~mL}$

Nearest integer $=109$
