For the reaction 2 HCl + Na2CO3 → 2 NaCl + H2O + CO2 8.0 moles of CO2 is collected at STP. What is the volume of CO2? 1) 57.6 L 2) 22.4 L 3) 0.0250 L 4) 2.80 L 5) 179 L 6) 0.357 L

Answer : The correct option is, (5) 179 L

Explanation : Given,

Moles of = 8.0 mole

The given chemical reaction is:

As we know that, 1 mole of substance occupy 22.4 L volume of gas at STP.

As, 1 mole of occupy 22.4 L volume of

So, 8.0 mole of occupy volume of

Thus, the volume of is, 179 L
