An alloy consists of nickel, zinc, and copper in the ratio 2:7:9.

Alexus [3.1K]

Answer:

0.4kg, 1.4kg and 1.8kg

Step-by-step explanation:

Given parameters:

Mass of alloy = 3.6kg

Ratio of elements in the alloy = 2:7:9

Unknown:

Mass of each element in the alloy = ?

Solution:

To find the mass of each element in the alloy, first find the sum of the ratio;

2+7+9 = 18

Mass of nickel = $\frac{2}{18}$ x 3.6 = 0.4kg

Mass of zinc = $\frac{7}{18}$ x 3.6 = 1.4kg

Mass of copper = $\frac{9}{18}$ x 3.6 = 1.8kg

The mass of each metal is 0.4kg, 1.4kg and 1.8kg
