Calculate the density of oxygen, O2, under each of the following conditions: STP 1.00 atm and 35.0 ∘C
Express your answers numerically in grams per liter. Enter the density at STP first and separate your answers by a comma. density at STP, density at 1 atm and 35.0 ∘C= g/L

  at STP, at 1 atm and

Explanation:

To calculate the density of gas, we use the equation given by ideal gas equation:

Number of moles (n) can be written as:

where, m = given mass

M = molar mass

where,

which is known as density of the gas

The relation becomes:

Density at STP :

M = molar mass of oxygen = 32 g/mol

R = Gas constant =

T = temperature of the gas = 273 K  (at STP)

P = pressure of the gas = 1.00 atm  (at STP)

Putting values in equation 1, we get:

Density at 1 atm and :

M = molar mass of oxygen = 32 g/mol

R = Gas constant =

T = temperature of the gas =

P = pressure of the gas = 1.00 atm

Putting values in equation 1, we get:
