Asap step by step I did try solving this and I got 4.1 which is wrong so if you could tell me what I did wrong

Question

If 10 g of oxygen gas is in a 2.00 L container at 50 Cwhat is the pressure in the container ? Round to one decimal place. Don’t forget oxygen is diatomic

Answer 1

You did it correctly to get pressure in atmospheres.

Using the Ideal Gas Law PV = nRT, solve for "P":

P = nRT/V

To calculate "n", divide the mass (10 g) by the molar mass (15.999 x 2 = 31.998 g/mol) to get n = 0.3125 moles

R = 0.0820575 L•atm/(K•mol) ←Look up in a reference book or google it.

T = 50°C + 273.15 = 323.15 K

V = 2.00 L

P = (0.3125)(0.0820575)(323.15)/2.00 = 4.1 atm

It is possible that you are being asked to provide pressure in KPa or Pa. To convert to KPa, multiply atm by 101.325 so 4.1435 atm = 419.8 KPa. To get pressure in Pa, multiply that value by 1000 to get 419842.3 Pa
