Answer:
1 L
Explanation:
ppm means parts per million. Generally the relationship between mass and litre is given as;
1 ppm = 1 mg/L
This means that 1 ppm is equivalent to 1 mg of a substance dissolved in 1 L of water.
Answer: D. Use tools to help improve their senses when they make observations.

Explanation:
Percent yield is 108.3%
<u>Explanation:</u>
Percent yield is the ratio of experimental yield and the theoretical yield multiplied by 100.The expression for the percent yield is given as,
Percent yield =
It is given that the experimental or actual yield is 3.9 g and the theoretical yield calculated using stoichiometry is 3.6 g, then the percent yield is calculated as,
Percent yield =
So the percent yield is 108.3%.
You divided them both by 108 to get 125/32. you cant just leave it like that though. You turn it into a mixed number. So the correct answer is 3 29/32
