Question

CH4+4S-CS2+2H2S
how many moles of CS2 can be formed by the complete reaction of 10.6 mol of S ​

Answer 1

Let's check the equation

$\\ \sf\longmapsto {CH_4\atop 1mol}+{4S\atop 4moles}\longrightarrow {CS_2\atop 1mol}+{2H_2S\atop 2moles}$

• 4moles of S gives 1 mol of CS2
• 1mol of S gives 1/4=0.25mol of CS2
• 10.6mol of S gives:-

$\\ \sf\longmapsto 10.6(0.25)=2.65moles\:of\:CS_2$
