calculate the moles of hydrogen present in 500ml sample of hydrogen gas at a pressure of 1 bar and 27 |
|
Answer» Answer:SOLUTION: The data given in the problem isP = 760mm of HG = 1 ATM V = 500cm3 T = 270C T = 27+ 273 = 300 K R = 82.1 cm3 K-1mol-1 number of moles of HYDROGEN (n) = ? According to ideal gas equation PV= nRT n = PV/RT = 1 atm X 500 cm3 /82.1 cm3 K-1mol-1 X 300 K n = 0.023mol
