Question

The density of dry air measured at 25 Celsius is 1.19 times 10 to the negative 3 what is the volume of 50.0g of air

Answer 1

Answer:

4.2 x 10⁴ mL

Explanation:

Data Given:

Density (d) of air =  1.19 x 10⁻³g/mL

Mass of the air (m) = 50 g

Volume of the air (V) = ?

Solution:

Formula will be used

                d = m/V

As we have to find volume so rearrange the above equation

               V = m/d . . . . . . . . . . . (1)

Put values in above equation 1

                V = 50 g / 1.19 x 10⁻³g/mL

                V = 4.2 x 10⁴ mL

So,

volume of dry air = 4.2 x 10⁴ mL
