6. Assume that coal can be represented by the formula C135H96O9NS
What is the percent of nitrogen by mass in this coal?
If three tons of coal were burned completely, what mass of nitrogen in NO would be produced.
Please show calculations.
7. This unbalanced equation represents the las step in the production of pure silicon for use in solar cells.
Mg (s) + _ SiCl4 (l) ---->_ MgCl2 (l) + _ Si (s)
6a) What is the percent of nitrogen by mass in this coal
I. Look up the atomic masses for each of the elements in the formula:-
C - 12.01 H - 1.01 O - 16.00 N - 14.01 S - 32.06
II. Determine how many grams of each element are present in one mole of C135H96O9NS:-
C - 135 moles x 12.01 g/mole = 1621.35 g
H - 96 moles x 1.01 ...
The percent by mass calculations are determined.
