Answer:
= 155 ppm
Explanation:
PPM also refers to parts per million, it represents a low concentration of a solution. It represents 0.001 gram or a milligram in a 1000 mL, equivalent to 1 mg per liter
Given that;
101 mg of Ca in 650.0 g of water
1 ppm = 1 mg/L
650 g = 650 mL = 0.65 L
Therefore;
= 101 mg/ 0.65 L
= 155.38 mg/L
<u>= 155 ppm</u>
The curved movement of air or water is the result of which of these:
The answer is B
Answer:
The answer to your question is: T2 = 235.44 °K
Explanation:
Data
V1 = 3.15 L V2 = 2.78 L
P1 = 2.40 atm P2 = 1.97 atm
T1 = 325°K T2 = ?
Formula
Process
T2 = (P2V2T1) / (P1V1)
T2 = (1.97x 2.78x 325) / (2.40 x 3.15)
T2 = 1779.895 / 7.56
T2 = 235.44 °K
Answer:
a warm air mass is caught between two colder air masses. The colder air moves under the warmer air pushing it up and then moves forward until it meets a mass that is warmer and pushes it up too.
The answer is B
Hope this helped. Good luck!
