If the pressure, volume, and the number of moles of a gas are known, which is needed to calculate the universal gas constant from the ideal gas law?
the temperature of the gas
the molar volume of the gas
the molar mass of the gas
the partial pressure of the gas

To calculate the universal gas constant from the ideal gas law, we need temperature of the gas

Explanation:

Ideal gas equation is the equation which is the relation between pressure, volume, number of moles and temperature of the gas.

The equation for an ideal gas is given by the relation:

where,

P = pressure of the gas

V = volume of the gas

n = number of moles of the gas

R = Universal gas constant

T = temperature of the gas

To calculate 'R', we need temperature for the given pressure, volume and number of moles.

Hence, to calculate the universal gas constant from the ideal gas law, we need temperature of the gas

indicate valleys, hills, steepness and gentleness of slopes.

explanation:

contour lines on a map indicate elevation, or depth. numeric notations on contour lines refer to the level of elevation, or height about sea level.

when the volume of gas is   changed from   717.73 ml   to 852 ml   the temperature will   change   from 315   c to 452   c

    calculation

this is calculated using the charles law formula

that is,   v1/t1 = v2/t2

          v1=?

        t1 = 315 c   into   kelvin = 315 +273 = 588 k

        v2 = 852   ml

        t2 = 425c + 273 =698 k

make v1   the subject of the formula ( by   multiplying both side by t1)

  v1=( v2 xt1) / t2

v1= (852 ml   x 588 k)/ 698 k= 717.73 ml
