i need help with this two problems(adsbygoogle = window.adsbygoogle || []).push({});

1. The problem statement, all variables and given/known data

calculate the pressure of 3.2gm of O_{2}gas in acontainer its volume 4000ml at 100^{o}C knowing that the molucul mass for O_{2}= 16u

2. Relevant equations

3. The attempt at a solution

PV=nRT

P=3.2x8.314x373x1000000 /(16x2x4000 )

1. The problem statement, all variables and given/known data

At atmospheric pressure and at 0^{o}C and the molecule mass for Nitrogen is 28 u so the volume for 1Kg mol equal

2. Relevant equations

3. The attempt at a solution

PV=nRT

V = 273x8.314 /28x1.o13x10^{5}
