Francium has a decay rate of 50% every 22 minutes. How much of an initial amount of 4.8 grams would be left after 88 minutes?

Jlenok [28]

Answer:

0.65g

Step-by-step explanation:

Decay rate = 50%

Decay rate = 0.5

$A = Aoe {}^{ - kt}$

where Ao = initial amount at start, k = rate of decay or growth, t = time, e = euler's number and A = value at time 't'

Ao = 4.8

t = 88/44 = 4

k = 0.5

substitute these values in the equation

$A = 4.8e {}^{ - 0.5 \times 4}$

$A = 0.6496$

$A = 0.65 \: (2dp)$

SOVA2 [1]

Answer:

T = 94.59 degree C

Step-by-step explanation:

Given data:

P= 83.4 kPa

$P= 83.4 \times 10^3 Pa \frac{1 bar}{10^5 Pa}$

P = 0.834 bar

for Saturated table

P = 0.8 bar T = 93.50 degree C

P = 0.9 bar T = 96.71 degree C

from interpolation method

$\frac{0.834 - 0.8}{0.9 - 0.8} = \frac{z}{96.71 - 93.5}$

z = 1.0914

T = 93.5 + z = 94.59 degree C
