<u>Answer:</u> The number of formula units in the given amount of magnesium carbonate is
<u>Explanation:</u>
Formula units is defined as lowest whole number ratio of ions in an ionic compound. It is calculate by multiplying the number of moles by Avogadro's number which is
We are given:
Number of moles of magnesium carbonate = 8.05 moles
Number of formula units =
Hence, the number of formula units in the given amount of magnesium carbonate is
Answer:
Explanation:
From the question, one can work out which states of matter to assign to which species. The trick with organic equations of this nature is to try to balance everything but oxygen first. Make sure you balance oxygen last because it is the easiest to balance.
Answer:
65.18% is the percent yield for this reaction.
Explanation:
Moles of salicyclic acid =
According to reaction 1 mole of salicyclic acid gives 1 mole of aspirin .
Then 0.01449 mole of salicylic acid will give :
of asprin
Mass of 0.01449 moles of aspirin :
= 0.01449 mol × 180 g/mol = 2.6082 g
Theoretical yield of aspirin = 2.6082 g
Experimental yield of aspirin = 1.7 g
The percent yield for this reaction:
65.18% is the percent yield for this reaction.
