hi
1 mile is 1 609 meters. (rounded).
As there is 100 centimeters in a meter, then
1 mile is 160 900 centimeter.
Then 1.5 miles , is 1 mile + one half so :
160 900 + 160 900 /2 = 160 900 + 80 450
= 241 350
1.5 mile is 241 350 centimeters.
please note that the value of a mile was rounded.
Answer:
The answer is: the body contains chemicals called buffers that resist changes in pH
When you exercise vigorously, the muscle will produce more carbon dioxide which will makes the blood more acidic. Human blood have some mechanism that could prevent the blood pH to stray further from the optimal range. One of the buffer that keep carbon dioxide acidity would be sodium bicarbonate.

Answer:
What I've done:
Molar mass of Zn: 65.409 g/mol
Molar mass of Cl: 2*35.453 =70.906 g/mol
Molar mass of O: 6*15.9994 =95.9964 g/mol
Total molar mass of Zn(ClO3)2: 232.3114 g/mol
21% of molar mass = 232.3114 g/mol
100% of mass = 1106.244762 g/mol
Molar mass of H2O: 18.01528 g/mol
232.3114 g/mol + 18.01528 g/mol = 250.32668 g/mol
250.32668 = 1106.244762
1106.244762 g/mol divided by 232.3114 g/mol
x = 4.419
Explanation:
% anything = (g/total mass)*100 = ?
Atomic mass Zn = 65.4 from your post.
molar mass Zn(ClO3)2 from your post = 232.3
molar mass H2O = 18
The 21.5% Zn is (note you used 21%) percent Zn in the hydrate so
%Zn = [(65.4)/(232.3 + x*18)]*100 = 21.5%
Solve for x and I obtained 3.99 which rounds to 4.00. Let me know if you don't understand any part.
