Argon has density 1.8 kg/ $m^{3}$ at $2 7^{\circ}$ C and 75 cm Hg. Find the mass of argon in a 200 $c m^{3}$ bulb at 75 cm Hg when the gas is at $17 7^{\circ}$ C, in units of $1 0^{- 4}$ kg (two decimals).

Answer:

2.40

Solution:

At the same pressure $ρ \propto \frac{1}{T}$ .

$ρ_{2} = 1.8 \times \frac{300}{450} = 1.2$ kg/ $m^{3}$ .

$m = 1.2 \times 2 \times 1 0^{- 4} = 2.40 \times 1 0^{- 4}$ kg.
