At normal temperature and pressure, air has
a density of 0.001184 g/mL. What is the mass
of air in a room that is 3.63 m by 2.97 m by
3.39 m? Answer in kg.

Respuesta :

The mass of air is 43.3 kg.

V = lwh = 3.63 m × 3.39 m × 2.97 m = 36.55 m³

V = 36.55 m³ × [tex] (\frac{100 cm}{1 \text m})^{3} [/tex] × [tex] \frac{1 mL}{ 1 cm^{3}} [/tex] = 3.655 × 10⁷ mL

Mass of air = 3.655 × 10⁷ mL × [tex] \frac{0.001184 g}{1 mL} [/tex] = 43 300 g = 43.3 kg
