Question

a 433 l tank holds helium gas at -48 °c with a pressure of 1.24 atm. how many moles of gas are in the tank?

Answer 1

Number of moles of gas are in the tank is  0.287 mole.

Pressure is the force implemented perpendicular to the floor of an object in step with unit location over which that force is shipped. Gauge strain is the strain relative to the ambient strain. diverse units are used to specific strain.

Strain is described as force implemented consistent with unit area. Mathematically it's far given by, P=FA. wherein F is the force acting perpendicular to the floor vicinity A. the usual unit of strain is the pascal (Pa), equal to at least one newton in keeping with meter squared (N/m 2 ).

Calculation:-

volume =  433 L

Pressure =  1.24 atm

T = -48 °c

  = 273 - 48 K

  = 225 K

PV = nRT

n = PV/RT

   = 1.24 × 433 / 8.314 × 225 K

   = 0.287 mole
