Question

one gallon of gasoline (3785 ml) has a mass of 2640 g. what is the density of gasoline​

Answer 1

Answer:

d = 0.6975 g/cm³

Explanation:

d = m/V       d = density      m = mass      V = volume

1 mL = 1 cubic centimeter

d = 2640 g / 3785 cm³

d = 0.6974900925 g/cm³

four significant digits in problem, so four significant digits in answer

Answer 2

• Mass=2640g
• Volume=3785mL

$\\ \rm\rightarrowtail Density=\dfrac{Mass}{Volume}$

$\\ \rm\rightarrowtail Density=\dfrac{2640}{3785}$

$\\ \rm\rightarrowtail Density=0.697g/mL$
