200.0 mL =0.2000 L
Molarity = number of mole solute / volume solution(L) = 0.50 mol/0.2000 L=
= 2.5 mol/L =2.5M
Answer : 2.5 M
Answer:
A molecule is an electrically neutral group of two or more atoms held together by chemical bonds. Molecules are distinguished from ions by their lack of electrical charge. hope this helps :)
For each carbon, hydrogen and nitrogen. You have to divide each percentage by its atomic mass.
C = 53.5/12.0107 = 4.45436
H = 15.5/1.00794 = 15.377899
N= 31.1/14.0067 = 2.220365
Round the number to significant figures
C = 4.45
H =15.4
N =2.22
Divide Each Number by the smallest number out of the three
so N = 2.22/2.22 =1
H = 15.4/2.22= 6.9 =7
C = 4.45/2.22= 2
So the Formula Should Be <span>C2H7N</span>

Answer:
Activating a glow stick is the example of a chemical change, as snapping one will cause a chemical reaction, causing the glow. All of the other options are physical changes because nothing new is formed. Hope this helps!
