Water consists of hydrogen and oxygen, and the approximate ratio, by mass, of hydrogen to oxygen is 2:16. Approximately how many grams of oxygen are there in 126 grams of water? | [
"112",
"72",
"16",
"142"
] | A | Solution:
We are given that the ratio of hydrogen to oxygen in water, by mass, is 2 : 16. Using our ratio multiplier we can re-write this as 2x : 16x. We can now use these expressions to determine how much oxygen is in 126 grams of water.
2x + 16x = 126
18x = 126
x = 7
Since x is 7, we know that there are 16 x 7 = 112 ... | AquaRat_train |
