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.

There are required 8 g of W and 4 g of X

Explanation:

Hi, first this is what we know:

a) W, X and Y are used in a 2:1:3 ratio to produce Z, meaning this that for each  gram of X used, 2 grams of W and 3 of Y are required.

b) Also, for each gram of X: 1 g X + 2 g W + 3 g Y= 6 g Z

Being that said, to produce 12 g  of  Z:

Following the ratio described in a) for the 12 g of Z 4 g W and 6 g Y are required.

On the other hand, to make those 6 g Y you required 4 g of W and 2 g of X

So, the total mass of W and X is :

you gotta add the following molecules so we can give u an answer
