If I start with 5 grams of #C_3H_8#, what is the theoretical yield of water in the equation #C_3H_8 + 5O_2 -> 3CO_2 + 4H_2O#?

Answer:

#~~8.18gm#

Explanation:

the molar mass of#C_3H_8=3xx12+8xx1=44gmmol^=1#
molar mass of water=#18gmmol^-1#

As per the equation 44 gm#C_3H_8# gives #4xx18=72gm# water
1gm #C_3H_8# gives #4xx18=72/44gm# water
5gm #C_3H_8# gives #4xx18=72/44xx5~~8.18gm# water
