The Himalaya mountain range stretches about 2,400 km from Tibet into Pakistan. It began forming when the Indian plate collided with the Eurasian plate. The pressure of the colliding plates forced the crust upward, folding, bending, and twisting rock. The Indian plate still moves north at a rate of about 5 cm/year, which is faster than your fingernails grow. Some mountains in the Himalayas lift up at a rate of 10 mm/year 1. At which type of plate boundary did the Himalayas form?​

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

this is not my own answer, this is an answer for the same question by the user blahblahmali. i do not claim ownership of this account.
