The total mass of the protons is 1.338 * 10^-23 g
<h3>What is a proton?</h3>
A proton is the positively charged particle in an atom. It is found in the nucleus along with the neutrons and are collectively called the nucleons.
The hydrogen atom has only one proton while the nitrogen atom has seven protons. Thus makes a total of eight protons in the ammonia molecule.
Hence, the total mass of protons in the ammonia molecule =
8 ( 1.673 × 10^-24 g) = 1.338 * 10^-23 g

Explanation:
Answer : The time passed in days is 28.6 days.
Explanation :
Half-life = 14.3 days
First we have to calculate the rate constant, we use the formula :
Now we have to calculate the time passed.
Expression for rate law for first order kinetics is given by:
where,
k = rate constant =
t = time passed by the sample = ?
a = let initial amount of the reactant = 100 g
a - x = amount left after decay process = 100 - 75.0 = 25.0 g
Now put all the given values in above equation, we get
Therefore, the time passed in days is 28.6 days.
