Question

48.8g of alloy contains 5 parts of copper and 3 parts of zinc by weight. find the weight of each part. Also find the percentage of each part.

please answer by its equation ​

Answer 1

Given :

• Mass of the Alloy = 48.8 g
• Alloy is composed of : Copper and Zinc
• Ratio of Copper and Zinc = 5:3

To Find :

• The weight of Copper and zinc in the alloy

Let's Assume :

Let's Assume that, the mass of copper = 5x

Mass of Zinc = 3x

So, we will calculate the other quantities on the basis of this.

Solution :

Given, Mass of copper(Assumed) = 5x

Mass of zinc(Assumed) = 3x

So, Total mass of Alloy = 48.8g ,

So, writing this as equation:

$\displaystyle \rm \implies 5x + 3x = 48.8g$

$\displaystyle \rm \implies 8x= 48.8g$

$\displaystyle \rm \implies x= \frac{48.8}{8}$

$\displaystyle \rm \implies x= 6.1g$

So, the value of Variable = 6.1g

This means that :

• Weight of Copper = 5×6.1 = 30.5g
• Weight of Zinc = 3×6.1 = 18.3 g

Final Answer:

We got that :

• Mass(Weight) of Copper = 30.5g
• Mass(Weight) of Zinc = 18.3g

Answer 2

Step-by-step explanation:

Direct Answer

Mass(Weight) of Copper = 30.5g

Mass(Weight) of Zinc = 18.3g
