Answer:
1. 14%
2. 98%
3. 52%
4. 13%
5. 39%
6. 28%
7. 20%
8. 37%
9. 17%
10. 19%
Step-by-step explanation:
To get a percentage divide the small number by the big number and then multiply by 100.
1. 28/200 = 0.14 * 100 = 14
2. 931/950 = 0.98 * 100 = 98
3. 364/700 = 0.52 * 100 = 52
4. 13/100 = 0.13 * 100 = 13
5. 273/700 = 0.39 * 100 = 39
6. 161/575 = 0.28 *100 = 28
7. 200/1000 = 0.2 * 100 = 20
8. 68/400 = 0.37 * 100 = 37
9. 68/400 = 0.17 * 100 = 17
10. 95/500 = 0.19 * 100 = 19

Given :
- In a neutral atom that has an atomic mass of 22 and atomic number of 12.
To Find :-
Solution :-
<u>As </u><u>we</u><u> know</u><u> that</u><u>,</u>
- n(neutrons) + n(protons) = A
- n(neutrons) + 12 = 2 2
- n(neutrons) = 22-12
- n(neutrons) = 10
<u>Hence </u><u>the</u><u> </u><u>required</u><u> answer</u><u> </u><u>is </u><u>1</u><u>0</u><u>.</u>
