How do i find the volume of a gas at stp if it’s volume is 80.0ml at 109kpa and -12.5 degrees celsius

Volume of the gas is 90.2 ml

Explanation:

Given:

Initial volume, V1 = 80.0 ml = 0.080 L

Initial pressure, P1 = 109 kPa = 1.076 atm ( 1 kPa = 0.00987 atm)

Initial temperature, T1 = -12.5 C = -12.5 + 273 K = 260.5 K

Under STP conditions i.e. standard temperature and pressure we have:

Pressure, P2 = 1 atm

Temperature, T2 = 273 K

Formula:

Based on the ideal gas relation we have:

every chemical equation adheres to the law of conservation of mass, which states that matter cannot be created or destroyed. therefore, there must be the same number of atoms of each element on each side of a chemical equation.

i'm wiling to try and you : )
