Data:

P (pressure) = 30 atm
V (volume) = 100.0 L
T (temperature) = 295 K
n (number of mols) = ?
R (<span>Gas constant) = 0.082 (atm*L/mol*K)
</span>
Formula: 

p*V = n*R*T

Solving:
p*V = n*R*T
30*100.0 = n*0.082*295
3000 = 24.19n
24.19n = 3000
n =  \frac{3000}{24.19}
\boxed{\boxed{n \approx 124.01\:mols}}\end{array}}\qquad\quad\checkmark

A sample contains 16. 75 g of the radioisotope U-236 and 50. 25 g of its daughter isotope, Th-232. How long did it take for deca
garri49 [273]

The time taken for the isotope to decay is 46 million years.

We'll begin by calculating the number of half-lives that has elapsed. This can be obtained as follow:

  • Original amount (N₀) = 50.25 g
  • Amount remaining (N) = 16.75
  • Number of half-lives (n) =?

2ⁿ = N₀ / N

2ⁿ = N₀ / N

2ⁿ = 50.25 / 16.75

2ⁿ = 3

Take the log of both side

Log 2ⁿ = 3

nLog 2 = Log 3

Divide both side by log 2

n = Log 3 / Log 2

n = 2

Finally, we shall determine the time.

  • Half-life (t½) = 23 million years
  • Number of half-lives (n) = 2
  • Time (t) =?

t = n × t½

t = 2  × 23

t = 46 million years
