If I use the dropped to add 10 mL of drink mix to 50 mL of water, what is the percent by volume of the drink mix in the solution
1 answer:
The percent by volume of the drink mix in the solution is 16.67%.
Explanation:
The formula used to determine the percentage by volume of the solute present in the solution is by finding the ratio of the volume of solute to the total volume of the solution multiplied by 100.
As in the present case, the solute is the drink mix and its volume is given as 10 mL. And the solution is the water. So the total volume of water is 60 mL.
Then the percentage by volume of the drink mix in the solution will be
So, the percent by volume of the drink mix in the solution is 16.67%.

Answer:
(a) ΔU = 7.2x10²
(b) W = -5.1x10²
(c) q = 5.2x10²
Explanation:
From the definition of power (p), we have:
(1)
<em>where, p: is power (J/s = W (watt)) W: is work = ΔU (J) and t: is time (s) </em>
(a) We can calculate the energy (ΔU) using equation (1):
(b) The work is related to pressure and volume by:
<em>where p: pressure and ΔV: change in volume = V final - V initial </em>
(c) By the definition of Energy, we can calculate q:
<em>where Δq: is the heat transfer </em>
