Question

Calculate the volume of water in gallons that 4.1 mL of water takes up. Express your answer in scientific notation,

Answer 1

Explanation:

The unit of volume derived from SI units(1) is the cubic meter, m3.

Chemists in a laboratory usually deal with much smaller volumes than cubic meters and the metric but non-SI units of liter or litre (L) and milliliter or millilitre (mL or ml) are in common use.

In 1964 the litre was redefined as being equal to exactly 1 cubic decimetre:

1 L = 1 dm3

So 1 milliltre = 1 cubic centimetre

1 mL = 1 cm3 (= 1cc)

Other metric units of measuring volume are given in the table below:
