Answer:
The difference in the amounts of carbon powder and ammonium carbonate is [tex]88.3\times 10^{-6}[/tex] grams.
Step-by-step explanation:
According to this statement, we have a mixture with [tex]3.7\times 10^{-6}[/tex] grams of carbon powder and [tex]92\times 10^{-6}[/tex] grams of ammonium carbonate. The difference between those amounts consist in subtracting the latter quantity for the former one. That is:
[tex]\Delta m = 92\times 10^{-6}\,g \,-\,3.7\times 10^{-6}\,g[/tex]
[tex]\Delta m = 88.3\times 10^{-6}\,g[/tex]
The difference in the amounts of carbon powder and ammonium carbonate is [tex]88.3\times 10^{-6}[/tex] grams.
