Question

1. What is the mass of 5.05 mL of air if the density of air is 1200.0 g/mL?

Answer 1

`\huge \boxed{\mathrm{6060 \ grams}}`

Step-by-step explanation:

`\sf \displaystyle density = (mass)/(volume)`

`\sf \displaystyle 1200 = (m)/(5.05)`

Multiplying both sides by 5.05.

`\sf \displaystyle 1200(5.05) = (m)/(5.05)(5.05)`

`\sf 6060=m`

The mass of the air is 6060 grams.

Answer 2

mass=?,volume=5.05,density=1200.

density=mass/volume.

1200=mass/5.05.

mass=1200×5.05=6060g
