The cost of one antacid is 2.325 cents per tablet.
<u>Explanation:</u>
As per the question based on the student analysis we know that,
Total antacid tablets in a bottle = 120
Purchase Price of a bottle = $ 2.79
Cost of 1 antacid tablet
As we know $1 = 100 cent
The cost of 1 antacid tablet = × 100 cents = 2.325 cents/tablet
.
Thus we came to know that it costs 2.325 cents/tablet .
Answer:
8.60 * atoms N2
Explanation:
We want to convert grams to moles and then moles to atoms.
First, we convert grams of nitrogen gas (which is N2) to moles. To do so, we need the molar mass of N2, which is just 14.01 * 2 = 28.02 g.
40 g N2 * = 1.43 mol N2
Now, we need to convert moles to atoms by using Avogadro's number, which is :
1.43 mol N2 * = 8.60 *
atoms N2
Thus, the answer is 8.60 * atoms N2.
