Answer 2

First of all, you're given with some information. Note it down like this:

Density of Helium = \(0.1755\ kg/m^3 \)
Volume of Helium in the Balloon = \(2,600 \ m^3 \)

Answer 3

In order to find the mass of Helium (in kgs) present in the balloon, you will have to use the formula for Density.

Do you know the formula for Density? If Yes, write it down. If No, let me know.

Answer 4

Mass/Volume

Answer 5

Good Work. So, we have:

\(\text{Density} = \cfrac{\text{Mass}}{\text{Volume}}\)

Plug-in the given values and find the mass.

Answer 6

Can you do that?

Answer 7

I'm not sure where to get mass

Answer 8

See you had Density = Mass/Volume.... right?

Now cross multiply that is :

Density * Volume = Mass

Are you getting my point?

Answer 9

453?

Answer 10

456.3* @mathslover

Answer 11

Yeah, 456.3 kg is the accurate answer.

Good Work.
