Question

S + 6 HNO3 --> H2SO4 + 6 NO2 + 2 H2O

Answer 1

#1

• 2 mol of water is made when 6mol of HNO3 are consumed.

Let moles of water can be made be x

$\\ \sf\longmapsto \dfrac{2}{6}=\dfrac{x}{28}$

$\\ \sf\longmapsto \dfrac{1}{3}=\dfrac{x}{28}$

$\\ \sf\longmapsto 3x=28$

$\\ \sf\longmapsto x\approx 9mol$

#2

Let moles of water can be made be x

$\\ \sf\longmapsto \dfrac{3}{2}=\dfrac{x}{76}$

$\\ \sf\longmapsto 2x=76(3)=228$

$\\ \sf\longmapsto x=114mol$
