5C₂ + 4SO₂ ------> 2CS₂ + 8CO
mole ratio of C₂ : CS₂
= 5 : 2
∴ since C₂ contains 8 moles
then CS₂ contain

moles
= 3.2 moles
Answer:
0.8 mL
Explanation:
Use the formula M1V1 = M2V2.
Plug the values in.
5(V1) = 0.02(200)
5V1 = 4
V1 = 0.8 mL
Hope this is right, correct me if I'm wrong!
1. 5 ethyl, 2 methyl octane
2. 1 ethyl, 2 methyl cyclopentane
3. 3,3,5,5- tetrafluoro heptane
4. 3,4-dimethyl hexene
5. 3,4-dimethyl cyclobutene
6. 3,5 diisopropyl cyclohexene
7. 3,3,4 trimethyl pentyne
8. 2,6 dibromo phenol
keep in mind that between 4-7, there could be #1 in front of the main name. for example with #4: 3,4-dimethyl-1- hexene. this honestly depends on the professor how he/she likes it. It is not necessary because if the number is not specified, it is assumed is #1
