Carbon 14 because it has an approximate half life of 5000 years.
Answer:
18.9 moles of MgCl2 = 17.834 kg of MgCl2
Explanation:
The molecular weight of MgCl is 80.0 g/mol . So, to convert the given mole amount to grams, multiply this by this number, which is constant for all compounds with a specific composition (mass fraction).
Considering the original question was in the context of chemistry, I wanted to make it seem formal and more educational too. Hopefully that worked!
EDIT: Came up with some text around what happens inside cells that would have made it better if someone just had an issue converting units, but I doubt my answer will be accepted >.<
Explanation:
Volume of the stock solution is
= ?
Initial concentration of ampicillin is
= 100 mg/ml
Final volume (
) = 30 ml
Final concentration of ampicillin (
) = 25 mg/ml
Therefore, calculate the volume of given stock as follows.
= 
Now, putting the given values into the above formula as follows.
= 
=
= 7.5 ml
Now, we will calculate the volume of water added into it as follows.
Volume of water added = 
= 30 ml - 7.5 ml
= 22.5 ml
Thus, we can conclude that required solution is 22.5 ml of deionized water.
