Explain how to count the elements, molecules, and atoms in the following formula: *
3CH3(CH2).CH3
Please Help Need answer ASAPP

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. : )

d.192

step-by-step explanation:

12*16=192

walter needs to make at least 5 more cookies but no more than 40. 5 ≥ x ≥ 40;

step-by-step explanation:

walter has to make a minimum of 20 cookies. he already has 15 cookies made, so he must make 5 more to meet the minimum.

the maximum amount of cookies he can make is 55. he already has 15, so he has to make no more than 40 more cookies to meet the maximum.
