We see that in 1 rock, there are 31 atoms of Argon and 1
atom of Potassium so the relative concentration of Potassium is:
1 / 32
or can be written as:
1 / 2^5
So this means that 5 half-lives have passed.
So the years are:
<span>years passed = 5 * 1.25 billion years = 6.25 billion years</span>
Typically the warm front is pushed upward and the cold pushed downward.
Answer:
50mL
Explanation:
Using Boyle's law equation as follows:
P1V1 = P2V2
Where;
P1 = initial pressure (torr.)
P2 = final pressure (torr.)
V1 = initial volume (mL)
V2 = final volume (mL)
According to the information provided in the question,
V1 = 25.0mL
V2 = ?
P1 = 760 torr.
P2 = 380 torr.
Using P1V1 = P2V2
V2 = P1V1//P2
V2 = (760 × 25) ÷ 380
V2 = 19000 ÷ 380
V2 = 50mL
