Answer:
0.737 L
Explanation:
Charles law states for a fixed amount of gas, volume of the gas is directly proportional to the absolute temperature of the gas at constant pressure
we can use the following equation
V1/T1 = V2/T2
where V1 is volume and T1 is temperature at first instance
V2 is volume and T2 is temperature at the second instance
substituting the values
3.50 L / 727.0 K = V2 / 153.0 K
V2 = 0.737 L
new volume at 153.0 K is 0.737 L
Answer:
<u>A weak acid</u> is an acid which dissociates partially in a solution to release few hydrogen ions while <u>A strong acid</u> is an acid which completely dissociates in solution to release many hydrogen ions.
Answer:
c) (12×0.9889) + (13×0.01108)
Explanation:
Given data:
Percentage of C-12 = 98.89%
Percentage of C-13 = 1.108%
Atomic mass = ?
Solution:
98.89/100 = 0.9889
1.108/ 100 = 0.01108
Atomic mass = (12×0.9889) + (13×0.01108)
Atomic mass = (11.8668 + 0.144034)
Atomic mass = 12.01084
