A gas has a volume of 590 mL at a temperature of -55 C. What volume will the gas occupy at 30 C?

750.550mL

Explanation:

V1/T1=v2/T2

V1=540mL

T1=-55°c to convert to Kelvin

273-55=218k

V2=?

T2=30°c to convert to Kelvin

273+30=303k

540/218=v2/303

Cross multiply

218v2=540×303

V2=540×303/218

V2=163620/218

V2=750.550mL

the ideal gas law equation is as follows

pv = nrt

where p - pressure

v - volume

n - number of moles

r - universal gas constant

t - temperature

so if the pressure, volume and temperature are already known

we are left with n and r

since r is the universal gas constant that has a known fixed value then r too is known

so we are left with 'n'

once we know temperature volume and pressure

we can find the number of moles of gas present using the ideal gas law equation
