Question

for the formula: CS2 + 3 O2 = CO2 + 2 SO2
what is the volume of SO2 gas formed when 2.00 moles of CS2 are burned and the reaction takes place at STP
1. 5.61 L
2. 22.4 L
3. 89.6 L
4. 44.8 L

Answer 1

help me please!!!!!!!!!!!!

Answer 2

First we have to deduce the moles from the CS2 to find the moles of SO2.
Because SO2 has 2 moles and CS2 is 1 mole, we will have to times CS2's moles by 2 to get the moles of SO2.

2 x 2 = 4mol of SO2

Now to find the volume of the gas in L, we have to times the moles by 22.4 L to get the litres of the gas.

4 x 22.4 = 89.6L

So the gas is 89.6L, meaning it is option 3 :)
I hope this helps!

Answer 3

thanks so much

Answer 4

Its alright :)
