The volume of helium in a blimp is 6.28 × 109 milliliters. the density of helium in the blimp is 0.1786 . find the mass of the helium in the blimp. (hint: 1,000 l = 1 cubic meter.)
a.
1,120 kg
b.
1.12 kg
c.
3.52 × 107 kg
d.
2,840 kg

1.12×10^6 Kg

Explanation:

Given volume = 6.28*10^9 mL

= 6.28*10^6 L (1)

Also, we are given specific density of helium = 0.1786

Specific density of helium = density of helium/density of water

0.1786 = density of helium/1000 Kg/m3

Density of helium = 0.1786*1000 Kg/m3

= 178.6 Kg/m3

Since 1000L = 1 m3

Density of helium =178.6/1000 Kg/L

Density of helium = 0.1786 Kg/L ...(2)

Hence,

Density = Mass/Volume

Mass = Density × Volume

Sub. Equation (1) and (2)

Mass = 6.28×10^6 ×0.1786 Kg

Mass = 1.12 ×10^6 Kg

the earth would become to overheated and everything alive on it will eventually die from overheating. plants will eventually die as well, water will evaporate, and it will be nothing but a hot planet without anything living on it.

you need to have a picture of the atom that way we can answer it
