How many moles are in 8.0 gram sample of C3H4

Sagot :

Answer:

0.18 mol C₃H₈

Explanation:

to find the mole you have to convert the 8.0grams into moles.

8.0g C₃H₈        1 mol C₃H₈

       1               44.0g C₃H₈

*Pretend that those are a table*

I got 44.0g because Carbon is 12.0g you multiply that 3 times because it has a subscript of 3 and do the same for Hydrogen (1.0 x 8) then add those which would be 44.0g.

1 mol of C₃H₈ = 44.0g C₃H₈

now just mulitply and divide them.

8.0g x 1 = 8.0

1 x 44.0g = 44.0

8.0/44.0 = 0.18 mol C₃H₈
