Question

A mixture contains 3.7 × 10–6 grams of carbon powder and 0.000092 grams of ammonium carbonate.

What is the difference in the amounts of carbon powder and ammonium carbonate?

Answer 1

The difference in the amounts of carbon powder and ammonium carbonate is
`88.3* 10^(-6)` grams.

Explanation:

According to this statement, we have a mixture with
`3.7* 10^(-6)` grams of carbon powder and
`92* 10^(-6)` grams of ammonium carbonate. The difference between those amounts consist in subtracting the latter quantity for the former one. That is:

`\Delta m = 92* 10^(-6)\,g \,-\,3.7* 10^(-6)\,g`

`\Delta m = 88.3* 10^(-6)\,g`

The difference in the amounts of carbon powder and ammonium carbonate is
`88.3* 10^(-6)` grams.
