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 =
x 3.6 = 0.4kg
Mass of zinc =
x 3.6 = 1.4kg
Mass of copper =
x 3.6 = 1.8kg
The mass of each metal is 0.4kg, 1.4kg and 1.8kg
G) Because 70% * 200 = 140
Answer:
False
