(7,5) = cos(4/5),
lal = 1,5) = 2, 12| = 3, then (a 5 2]
1)-18 2) 18//7 3)18/5 4) 18​

Answer 1

Answer:

• Now, to know the percent composition of Carbon and Oxygen . We will divide their weight with the total weight of CO2. % C = 12.01/44.01 = 0.2729= 27.29% (we will divide 0.2729 with 100 to take the percentage). % O = 32.00/44.01 =0.7271 =72.71 %O in CO2.
