Answer:

$3.55\times 10^{-4}\ kL$

Explanation:

Given that,

A typical coffee mug holds about 355,000 microliters of liquid.

$1\ \mu L=10^{-6}\ L$

Also, 1 L = 0.001 kL

$10^{-6}\ L=0.001\times 10^{-6}\ kL\\\\=10^{-9}\ kL$

So, a typical coffee mug holds about $355000 \times 10^{-9}\ kL$ or $0.000355\ kL$ of liquid.

We need to convert it into Scientific notation.

We will shift 4 zeros to right. As a result,

$V=3.55\times 10^{-4}\ kL$

So, the mug will hold $3.55\times 10^{-4}\ kL$ of liquid.
