Which are the statements?
Answer:
5.73mL of 50%
Explanation:
Let's say the amount of 50% solution to be used is, y
Therefore 37-y = the amount of 1/200 solution used
The set up will then be,
0.5y +0.05(37-y) = 1/6(30)
0.5y + 1.85 -0.05y = 5
0.55y = 3.15
y= 5.73mL of 50%
Answer:
I would say C, but if not then definitely D. Because energy is transferred through the environment or could be said as flows.
