15 gallons of 35% peroxide solution contains 0.35 × 15 = 5.25 gallons of hydrogen peroxide. The rest of the volume is made up of 15 - 5.25 = 9.75 gallons of water.
If we add gallons of water to the solution, the amount of hyrdrogen peroxide in the solution stays the same, but the volume of water increases to
gallons, and the total volume increases to
gallons.
To get a concentration of 8% in this diluted solution, we add gallons of water such that
Solve for .
To get the desired concentration, one must add 50.625 gallons of water, and one will end up with a total volume of 65.625 gallons of solution.
Answer:
The volunteers donated millimeters of blood.
Step-by-step explanation:
Given:
Total Number of Volunteers = 32
number of Volunteers failed to donate = n
Amount of blood donated by each volunteer = 470 mm
We need to find the Total amount of blood donated by the Volunteers.
Solution:
First we will find the number of volunteers donated blood.
the number of volunteers donated blood is equal to Total Number of Volunteers minus number of Volunteers failed to donate.
framing in equation form we get;
the number of volunteers donated blood =
Now we will find Total amount of blood donated by the Volunteers.
Total amount of blood donated by the Volunteers is equal to Amount of blood donated by each volunteer multiplied by the number of volunteers donated blood.
framing in equation form we get;
Total amount of blood donated by the Volunteers =
Hence The volunteers donated millimeters of blood.
