Question

The average mass of a grain of sand from
a certain beach is 9 × 10-8 kilograms.
What is this value in grams? Give your
answer in standard form.

Answer 1

Answer:

0.0009 grams

Step-by-step explanation:

The mass of the grain sand is:

$9 \times {10}^{ - 8} \: Kg$

To convert kilograms to grams we divide by 1000 (1 × 10³)

$\frac{9 \times {10}^{ - 8} }{1 \times {10}^{3} }$

Which gives us:

$9 \times {10}^{ - 5}$

$9 \times {10}^{ - 5} = 0.0009 \: g$
