Ответ:
the answer is false.
Explanation:
Ответ:
%N = 29.16 %
%H = 8.39 %
%C = 12.50 %
%O = 49.95%
Explanation:
Step 1: Data given
Molar mass of (NH4)2CO3 = 96.086 g/mol
Molar mass of N = 14.007 g/mol
Molar mass of H = 1.008 g/mol
Molar mass of C = 12.011 g/mol
Molar mass of O = 15.999 g/mol
Step 2: Calculate the percentage of the elements
% N = (2*14.007 / 96.086) *100 %
%N = 29.16 %
%H = (8*1.008 / 96.086) *100%
%H = 8.39 %
%C = (12.011 / 96.086) *100%
%C = 12.50 %
%O = (3*15.999/96.086) *100%
%O = 49.95%
