Question

a certain amount of N2 gas at 27°C is measured for pressure in a gas manometer. the pressure observed is 800 mm of Hg. If aqueous tension at this temperature is 20 mm of Hg. Find the mass of gas if its volume is 2 litres
Please Give me the correct solution..
what is the given mass of gas??​

Answer 1

Answer:

Number of moles of nitrogen gas = 28/28 = 1 mol

PV = nRT

T = PV/nR = (2.46 x 10) / 1 x 0.082

= 300 K

Answer 2

Answer:

Number of moles of nitrogen gas = 28/28 = 1

mol

PV = nRT

T = PV/nR

(2.46 x 10)/1 x 0.082

= 300 K
