Step-by-step explanation: its not a fraction, its a integer, its positive, and is rational (every integer is rational).
Answer:
Im positive that u wrote the formula wrong, theres no dot on a formula. What I understand on how to count each molecules is by the following
1) The coefficient in front of the molecules serves a type of multiplier, lets say 3 CO2, you take the 3 and multiply to each atom, so it would be 3 C and with O you do 3x2 cause 2 oxygen atom and it would become 6 O.
2) For the bracket lets say (CH3)2, Its the same thing as coefficient, the subscript 2 serves as a mulitplier, so there would br 2 C and 6 H
3) What happens if you have both the coefficient and subscript. Well, lets take an example of 2(NH3)2, you multiply everything together. So by doing the example, N would be 2 x 1( because theres 1 N) x 2( this being the subscript), which would be 4 N. For H, its 2 x 3(Because theres 3 H atoms) x 2(this being the subscript), which is equals to 12 H atoms.
Hope I didnt confuse you that much and asnwered your questipn, good luck in your future test. : )
