Answer:
The answer to your question is 33.4 ml
Explanation:
Data
volume 1 = V1 = 42 ml
temperature 1 = T1 = 20°C
temperature 2 = T2 = -60°C
Volume 2 = V2 = x
Process
1.- Convert celsius to kelvin
T1 = 20 + 273 = 293°K
T2 = -60 + 273 = 233°K
2.- Use the Charles' law to solve this problem
Solve for V2
V2 =
3.- Substitution
V2 =
4.- Simplification
V2 =
5.- Result
V2 = 33.4ml
<u>Answer:</u> The amount of sample left after 20 years is 288.522 g and after 50 years is 144.26 g
<u>Explanation:</u>
We are given a function that calculates the amount of sample remaining after 't' years, which is:
- <u>For t = 20 years</u>
Putting values in above equation:
Hence, the amount of sample left after 20 years is 288.522 g
- <u>For t = 50 years</u>
Putting values in above equation:
Hence, the amount of sample left after 50 years is 144.26 g
