Step-by-step explanation:
3(9+3⋅8)−23
3(12.8)-23
38.4-23
15.4
So the answer is15.4
Answer:
W = 9.33 grams
X = 4.67 grams
Step-by-step explanation:
Given;
Mass of Z to be made = 14 grams
Composition of Z
W:X:Y = 2:1:3
To make 6 grams of Y requires 4 grams of W and 2 grams of X
Composition of Y (for 6grams)
W:X = 4:2 = 2:1
Substituting the composition of Y to Z
Z = W:X:Y = 2:1:3
Z = W:X:W:X = 2:1:2:1
summing them up, we have;
Z = W:X = 4:2 = 2:1
Since the final mixing ratio for W and X are 2:1, to make 14 grams of Z, we need;
W = 2/3 × 14grams = 28/3 grams
W = 9.33 grams
X = 1/3 × 14grams = 14/3 grams
X = 4.67 grams
