1.025 moles of NaCl are present in a solution with a molarity of 8.20M and 125 mL of solution. Details about molarity can be found below.

<h3>How to calculate molarity?</h3>

The number of moles of a solution can be calculated by multiplying the molarity of the solution by its volume. That is;

no of moles = molarity × volume

According to this question, a solution has a molarity of 8.20M and volume of 125 mL of solution.

no of moles = 8.20 × 0.125

no of moles = 1.025moles

Therefore, 1.025 moles of NaCl are present in a solution with a molarity of 8.20M and 125 mL of solution.

1. Use the formula:

-kt = ln[\frac{FinalAmount}{InitialAmount}]

k = ln2 / half-life

So, t = - \frac{4.5}{ln2} \times ln[\frac{0.55}{1}]

t =  3.8 billion yr

2.  Same formula:

t = - \frac{4.5}{ln2} \times ln[\frac{0.63}{1}]

t = 2.93 billion yr.
