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

The volume of helium in a blimp is 6.28 \times 10^{9} millilitres. The density of helium in the blimp is 0.1786. Then the mass of the helium in the blimp is 1,120 kg

Option A

Explanation:

The ratio of amount of matter (mass) an object has and its volume is defined as density. If an object has more amount of matter, then it has more density. The formula for density is,

Given data,  

In blimp, helium’s volume =

              Helium’s density =

As per conversion factor, we know that

So, Helium’s volume will be

Rearranging the formula,  

hey there!

boiling point is the temperature at which the vapor pressure of the liquid equals atmospheric pressure. the vapor pressure of solvent molecules is decreased when a solute is added, so a higher temperature is required to increase the number of solvent molecules in the gas phase above the liquid.

at the freezing point, the vapor pressures of the solid and liquid are equal; a lower temperature is needed to reduce the number of solvent particles above the liquid.

the correct answer is:

a. formation of precipitation
