A typical coffee mug holds about 355,000 microliters of liquid. How many kiloliters of liquid does this mug hold expressed in st
skad [1K]

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.
