How many 2-tablespoon doses are in 4 bottles of medication containing 16 ounces each?
1 answer:
1 tablespoon = 0.5 ounces
We are required to find for 2 table spoons.
2 table spoons = 2 x 0.5 = 1 ounce.
Each bottle has 16 ounce.
Number of bottles = 4
So total number = 4 x 16 = 64 ounces.
Number of 2 table spoons =
= 64
Thus there are 64 2-tablespoon doses are in 4 bottles of medication containing 16 ounces each.

<u>Answer:</u> 0.0237 g of calcium carbonate would be required to neutralize the given amount of HCl
<u>Explanation:</u>
pH is defined as the negative logarithm of hydrogen ion concentration present in the solution
.....(1)
Given value of pH = 1.5
Putting values in equation 1:
Molarity is defined as the amount of solute expressed in the number of moles present per liter of solution. The units of molarity are mol/L. The formula used to calculate molarity:
.....(2)
We are given:
Volume of solution = 15.0 mL
Molarity of HCl = 0.0316 M
Putting values in equation 2:
The chemical equation for the reaction of HCl and calcium carbonate follows:
By the stoichiometry of the reaction:
2 moles of HCl reacts with 1 mole of calcium carbonate
So, of HCl will react with =
of calcium carbonate
The number of moles is defined as the ratio of the mass of a substance to its molar mass.
Moles of calcium carbonate =
Molar mass of calcium carbonate = 100.01 g/mol
Putting values in the above equation:
Hence, 0.0237 g of calcium carbonate would be required to neutralize the given amount of HCl
