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 2.84 m by 2.27 m by
2.71 m? (answer in units of kg)

0.001184 g/mL = 0.001184 x 1000 ml/L x 1/1000 kg/g
= 0.001184 kg/L

Volume of room:
2.84 x 2.27 x 2.71
= 17.47 m³ = 17470 L

Mass of air = density x volume
= 0.001184 x 17470
= 20.7 kg

There is no graph to look at on here, but i shall explain them to you. a line graph is just in its title it’s a graph with a line running through the dots to show an increase or decrease. a bar graph is used to show how much or how little something is so a comparison. a scatter plot is used to graph points to tell the data. and i don’t know what a histogram is.
