Answer:
Explanation:
We can use Dalton's Law of Partial Pressures:
Each gas in a mixture of gases equals its pressure separately from the other gases.
No! If it was 12% a 150 pound person would be about 18 pounds of salt!
~0.4%
The average 150lb person would contain ~280 g of NaCl.
The percentage of elements in the compound is determined from the number of elements in the compound
<h3>Further explanation </h3>
Proust states the Comparative Law that compounds are formed from elements with the same Mass Comparison so that compounds have a fixed composition of elements
Example
% Lithium (Li) in Li₂CO₃(lithium carbonate)
Ar of Li = 6.941 g/mol
MW of Li₂CO₃ = 73.891 g/mol
Catabolic reactions is the answer
