Answer:
760 mm of Hg
Explanation:
If the gases A , B and C are non reacting , then according to <u>Dalton's </u><u>Law </u><u>of</u><u> </u><u>Partial </u><u>Pressure</u> the total pressure exerted is equal to sum of individual partial pressure of the gases .
If there are n , number of gases then ,
Here ,
- Partial pressure of Gas A = 400mm of Hg
- Partial pressure of Gas B = 220 mm of Hg
- Partial pressure of Gas C = 140mm of Hg
Hence the total pressure exerted is ,
Substitute ,
Add ,
<u>Hence</u><u> the</u><u> </u><u>total</u><u> pressure</u><u> exerted</u><u> by</u><u> the</u><u> </u><u>gases </u><u>is </u><u>7</u><u>6</u><u>0</u><u> </u><u>mm </u><u>of </u><u>Hg</u><u>.</u>

The decay curve is a graph showing the relationship of the amount of a substance like Phosphorus-32 with respect to time. Through time, the amount decreases. If the curve was given, you will just have to locate the half of the original amount in the y-axis and connect it to the curve. Then, you move it downwards to the x-axis to determine the time. The time at which the amount of Phosphorus-32 left is reduced to half is called the half-life.
But this have been experimented and there is already an empirical value for this. The half-life of Phosphorus-32 is 14.29 days.
