A backpacker carries 2.5 L of white gas as fuel for her stove. How many pounds does the fuel add to her load? Assume the density of white gas to be 0.79 g/cnr5.
Solution 112 :
Volume of gas = 2.5 L
Density of gas = 0.79 g.cm3.
fuel added to load in pounds(lb) = ?
Mass of fuel is :
= Volume of fueldensity of fuel.
Here the volume of fuel is in L and density is in g/cm3. So,let’s convert the volume in L to cm3:
1 L = 1000 cm3
Therefore,2.5 L in cm3 is :
= 2500 cm3.
