1. Calculate the density of oxygen at STP using the ideal gas law.
1. Calculate the density of oxygen at STP using the ideal gas law. `ρ = m/V`
`ρ = 1.43\ kg//m^3`
Given:
STP
`V = 22.4 L = 22.4 times 10^(-3)\ m^3`
`n = 1\ mol`
atomic mass `am_(O_2) = 32.0 times 10^(-3) kg//mol`
equation:
`ρ = m/V`
Solution:
`m = 1\ mol times 32.0 times 10^(-3) kg//mol = 32.0 times 10^(-3) kg`
`ρ = m/V`
`ρ = (32.0 times 10^(-3)\ kg)/(22.4 times 10^(-3)\ m^3)`
`ρ = 1.43\ kg//m^3` |
