A flask with a volume of 125.0 mL contains air with a density of 1.122 g/L. What is the mass of the air contained in the flask?

The answer is

Explanation:

To find the mass of a substance given the density and volume we use the formula

From the question

Density = 1.122 g/L

volume = 125 mL

We must convert the volume from mL to L

1000 mL = 1 L

125 mL = 0.125 L

volume = 0.125 L

Substitute the values into the above formula and solve for the mass

That's

mass = 1.122 × 0.125 = 0.14025

We have the final answer as

periodic trends is an atom that gets larger as the number of electronic shells increase, the radius of atoms increases as you go down a certain group in the periodic table of elements. in general, the size of an atom will decrease as you move from left to right of a certain period.
