Answer:
35.48 uma
Explanation:
An isotope is when an element has equal numbers of protons but different mass value because it has different amount of neutrons.
To calculate the average atomic mass with the given data:
First change de percentages to fractional numbers, divide by 100.
Remember the sum of a percentage is equal to 100, but when you are adding the fractions the sum is equal to 1.
76/100 = 0.76
24/100 = 0.24
% fraction
76.00 0.76
24.00 0.24
total100.00 1.00
Now, multiply the mass with their corresponding fraction:
35(0.76) = 26.60
37(0.24) = 8.88
% fraction amu amu
76.00 0.76 35 26.60
24.00 0.24 37 8.88
total100.00 1.00 average 35.48
Now you add the calculated mass to obtain the average atomic mass of the element.
And the value you will get is 35.48 amu.
I included an excel table so you can review it, I like to organize all the given data and the calculation in tables, also I think is easier to understand.
They would make sure it gets lots of water and it needs sunlight to so some kind of source that could replace the sun
I think it’s c because it only includes the parts of the sentence involving the building and the sentence still makes sense
