Question 255570:
It is required to make 12 grams of certain chemical compound called Z. This is made from compounds W, X, and Y in the ratio of 2:1:3. The compound Y is itself made from W and X. To make 6 grams of Y requires 4 grams of W and 2 grams of X. How much W and X is required to make the required amount of Z.
You can put this solution on YOUR website! It is required to make 12 grams of certain chemical compound called Z. This is made from compounds W, X, and Y in the ratio of 2:1:3. The compound Y is itself made from W and X. To make 6 grams of Y requires 4 grams of W and 2 grams of X.
The ratio W:X:Y = 2:1:3
W:X:Y = 4:2:6
But 6 grams of Y contains 4 grams of W and 2 grams of X.
Therefore 6 grams of Y can be replaced by 4 grams of W and
2 grams of X.
Therefore 12 grams of Z contains 4+4 = 8 grams of W
And 12 grams of Z contains 2+2 = 4 grams of X
