NEET levelSingle correct optionDifficulty 1 of 3mc037

In the reaction $N X_{2} + 3 H X_{2} 2 NH X_{3}$ , how many moles of $NH X_{3}$ are formed from $6$ mol of $H X_{2}$ with excess $N X_{2}$ ?

3

mol

H X_{2}

gives

2

mol

NH X_{3}

. So

6

mol

H X_{2}

gives

6 \times 2/3 = 4

mol

NH X_{3}
