In a science experiment, chemicals X, Y, and Z are mixed in the ratio 5:2:3. If the total weight of the mixture is 100 grams, how much of chemical Y is present?
20 grams
The ratio of X : Y : Z is 5 : 2 : 3, so the total number of parts is \(5 + 2 + 3 = 10\).
Chemical Y corresponds to 2 parts out of 10.
Weight of Y \(= \frac{2}{10} \times 100 = 20\) grams.
Hence, 20 grams of chemical Y is present in the mixture.
