Answer:
Tube 2 has a total dilution of 1:50
Explanation:
We have a 2 ml serum sample added to a 18 mL phosphate buffered saline sample in tube 1. This means now in tube 1 there is 20 mL.
We have a 1:10 (= 2:20) dilution here.
10 ml of this 1:10 diluted tube 1 is taken and added to a 40 mL of PBS in tube 2.
Now we have 50 mL in tube 2.
This is a 10:50 (= 1:5) dilution.
The total dilution is 10x5 = 50
So the total ditultion has a rate 1:50
Tube 2 has a total dilution of 1:50
Answer:
-2
Explanation:
carbonate oxifation number is -2
It would be 4.6cgL not sure tho because I didint do that good in this
Ne is the smallest
B is the biggest
It goes (smallest to largest) : Ne, F,C,B
10 seconds = 8grams
then just divide by 2 another 4 times...
= 0.5grams after 50 seconds
