A student analyzed an antacid tablet from a bottle containing 120 tablets purchased for $2.79. The mass of the tablet was 1.247
1 answer:
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 .

<u>Answer:</u> The mass of carbon dioxide produced is 26.9 kg
<u>Explanation:</u>
To calculate the number of moles, we use the equation:
.....(1)
Given mass of propane = 9 kg = 9000 g (Conversion factor: 1 kg = 1000 g)
Molar mass of propane = 44.1 g/mol
Putting values in equation 1, we get:
The chemical equation for the combustion of propane follows:
By Stoichiometry of the reaction:
1 mole of propane produces 3 moles of carbon dioxide.
So, 204.08 moles of propane will produce = of carbon dioxide.
Now, calculating the mass of carbon dioxide by using equation 1, we get:
Molar mass of carbon dioxide = 44.01 g/mol
Moles of carbon dioxide = 612.24 moles
Putting values in equation 1, we get:
Hence, the mass of carbon dioxide produced is 26.9 kg
Answer: 0.377 moles of calcium chloride will be formed.
Explanation:
To calculate the moles :
The balanced chemical reaction is:
According to stoichiometry :
As 1 mole of give = 1 mole of
Thus 0.377 moles of give =
of
Thus 0.377 moles of calcium chloride will be formed upon the complete reaction of 27.9 grams of calcium hydroxide with excess hydrochloric acid
