Question

The lung capacity of the blue whale is 5100L. Convert this volume into gallons. Express your answer to two significant figures and include the appropriate units.

Answer 1

By definition, we have that the conversion of a US gallon to liters is given by:
1 liter = 3.78541 gallons
Therefore, we can apply the following rule of three:
1 liter ---------------------> 3.78541 gallons
5100 liters --------------> x
Clearing x we have:

`x = (5100) * (3.78541) x = 19305.591`
two significant figures:

`x = 19000`
Answer:
The lung capacity of the blue whale is:

`x = 19000 gallons`
