Answer 1

Q167566

Convert $4.52/gal to ¢/mL

with the correct number of sig figs and units.

Solution:

For converting $4.52/gal to ¢/mL, we will require two conversion factors.

One for converting '$' to '¢' and

second for converting 'gal' to 'mL'.

1 dollar = 100 cent and 1 gallon = 3785 mL.

Using both this conversion factor we can convert $4.52/gal to ¢/mL.

$cent/mL = \frac{4.52 dollar }{1 gallon} * \frac{100 cent }{ 1 dollar} * \frac{1 gallon }{3785 mL } = 0.119 cent /mL$

which can also be written as 0.119 ¢/mL.

In the question, we are given $4.52/gal in 3 significant figures.

So our final answer must also be in 3 significant figures.

So the final answer is 0.119 ¢/mL.
