Question

what is the value of pv for 11.2 litre of an ideal gas at STP?​

Answer 1

Answer:

1.12

Explanation:

number of moles=0.5

pv=nRT

Answer 2

Answer:

1247.1 j

Explanation:

Value of PV for 11.2 litre of an ideal gas at stp is equal to 1247.1 joules

1. We know, PV =nRT

2. 11.2 litres mean 0.5 moles as 22.4 litres is the volume occupied by 1 mole of a gas at STP

3. Also, at STP , T = 300K

4. Thus, PV = 0.5 * 8.314 * 300

= 1247.1 (N/m^2) *m^3

= 1247.1 Nm

= 1247.1 J
