Answer:
17.04%
Explanation:
Actual Value = 173.1
Measured Value = 143.6
Percent error is obtained using the equation;
Percent error = (Measured - Actual) / Actual ]* 100
Percent error = [ (143.6 - 173.1) / 173.1 ] * 100
The absolute value of (Measured - Actual) is taken,
Percent Error = [29.5 / 173.1 ] * 100
Percent Error = 0.1704 * 100 = 17.04%
Answer:
35.4575 amu
Explanation:
We use the relative abundance of each of the isotopes.
Let the isotopes be A and B.
Since A is having an abundance of 75.53, the abundance of B would be 100 - 75.53 = 24.47%
The average atomic mass is calculated as follows;
(75.53/100 * 34.96885) + (24.47/100 * 36.96590) = 26.4119 + 9.0456 = 35.4575 amu
