As we know that, PV = nRT
or PV = (m/M) RT
or PM = (m/V) RT = d RT
In condition (1): PV = d R 300
In condition (2): PV = 0.75d RT
Dividing condition (1) by (2), we get:
1 = (300)/0.75T
or T = 400 K

The density of a gas at 27°C can vary depending on the specific gas and its conditions. However, in general, the density of a gas can be calculated using the ideal gas law. The ideal gas law states that:
PV = nRT
Where:
P = pressure of the gas
V = volume of the gas
n = number of moles of gas
R = ideal gas constant
T = temperature in Kelvin
To calculate the density of a gas, we need to rearrange the ideal gas law to solve for density:
density = (n * M) / V
Where:
density = density of the gas
M = molar mass of the gas
Keep in mind that the temperature needs to be converted from Celsius to Kelvin by adding 273.15.
So, to calculate the density of a gas at 27°C, you would need to know the specific gas and its molar mass, as well as the pressure and volume of the gas.
