Question

I think this may be 29.8

Answer 1

There are 1000 mL in a Liter.

0.298 mL * 1 L/1000 mL = 0.000298 L

That makes the answer D

You could put in your calculator like this (if that is the problem)

0.298

÷

1000

=

0.000298

I have two calculators. One registers that as the answer and the other one changes into scientific notation

2.98 * 10^-4.

10^-4 requires 3 zeros after the decimal to get rid of 10^-4

0.000298 get's rid of the 10^-4 if that is what your calculator gives you.

Answer 2

Note that 1000 ml = 1 liter.

Thus,

0.298 ml             1 liter

--------------- * ------------------ = 0.000298 liter

      1                1000 ml
