The density of no2 in a 3.50 l tank at 780.0 torr and 37.0 °c is g/l.

The density of nitrogen dioxide in a 3.50 L tank at 780.0 Torr and 37.0 °C is 1.86 g/L.

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:

   .....(1)

We are given:

M = molar mass of argon = 46 g/mol

R = Gas constant =

T = temperature of the gas =

P = pressure of the gas = 780.0 Torr=

1 atm = 760 Torr

Putting values in equation 1, we get:

The density of nitrogen dioxide in a 3.50 L tank at 780.0 Torr and 37.0 °c is 1.86 g/L.
