Answer:
119.9 pound
Explanation:
Given data:
Density of gasoline = 0.749 g/mL
Volume of gasoline = 19.2 gal (19.2× 37854 =72679.9 mL)
Mass = ?
Solution:
Density:
Density is equal to the mass of substance divided by its volume.
Units:
SI unit of density is Kg/m3.
Other units are given below,
g/cm3, g/mL , kg/L
Formula:
D=m/v
D= density
m=mass
V=volume
Now we will put the values in formula:
d = m/v
0.749 g/mL = m/ 72679.9 mL
m = 54437.25 g
gram to gallon:
54437.25/ 454
m = 119.9 pound
The correct answer is b :)
That looks like cells of a multicellular organism, so B.
