Question

6×10^20 molecules are present in hydrogen gas,have volume V at STP. find the volume of oxygen which has 3×10^24 molecules at STP.​

Answer 1

Answer:

here we will use the equation

PV= nRT

partial pressure of gas × volume of gas = moles of gas × R(universal gas constant) × T (temperature of gas)

at stp temperature and pressure is constant

this means that volume of gas is directly proportional to the moles of the gas
