Aweather balloon is filled with 200l of helium at 27 degree celsius and 0.950 atm. what would be the volume of the gas at -10 degrees and 0.125 atm?

The volume when the pressure and temperature has changed is 1332.53 L

Explanation:

To calculate the volume when temperature and pressure has changed, we use the equation given by combined gas law. The equation follows:

where,

are the initial pressure, volume and temperature of the gas

are the final pressure, volume and temperature of the gas

We are given:

Putting values in above equation, we get:

Hence, the volume when the pressure and temperature has changed is 1332.53 L

so here we go

atomic mass

239 + 1 = y + 134 + 3 combine like terms

240 = y + 137             subtract 137 from both terms

240 - 137 = y

103 = y

atomic number

94 = z +54 + 0

94 = z + 54               subtract 54 from both sides.

40 = z
