1.59 x 10^-18

Step-by-step explanation:

The mass of the 30,000 molecules is 1.59 x 10^-18

Given this information,

- There are 30,000 molecules.

- And, the mass of one molecule of oxygen i.e. 5.3 x 10^-18 grams.

Based on the information above, the calculation is this:

= 30,000 x 5.3 x 10^-23

= 3 x 10^4 x 5.3 x 10^-23

= 1.59 x 10^-23+4

= 1.59 x 10^-19

= 1.59 x 10^-19 x 10

= 1.59 x 10^-18

Therefore, we can determine that the mass of 30,000 molecules is 1.59 x 10^-18.

I hope this helped!

the least value out of the data shown is 5, maybe if you post a picture with it i could a little more.
