Density in STP, density in 1 atm, and 35 C = 1.43, 1.31 g/L. the amount from something per unit of length, area, or mass.
Density is a measure of just how much “things” is really in a given quantity of space. For instance, a block of the harder, lighter metal gold (Au) will be heavier than a block of the lighter element lead (Pb) (Au). Styrofoam blocks are less dense than bricks. Its definition is the mass per unit volume.
Density is an important concept because it allows us to forecast which compounds would float and will sink inside a liquid. Generally, if an object's density is less than its own, it will float.
At STP,
Molar mass =32 g=0.032 kg
T=273.15 K
P=100kPa
PM=(ro)* RT
ro=PM/RT=(10^50.032)/(8.314273.15)=1.409
density=1.409 kg/m^3= 1.43g/L
Molar mass =32 g=0.032 kg
T=273.15 +25= 298.15 K
P=101.325 kPa
PM=(ro)* RT
ro=PM/RT=(1013250.032)/(8.314298.15)=1.308
density=1.308 kg/m^3 =1.31 g/L
