the ratio of metal A and metal B in an alloy is 5:7 find the weight of metal A in 14.4g wt of the alloy
Answers
The answer is 6.0 grams
GIVEN
Ratio of metal A and metal B in an alloy is 5:7
Total weight of alloy = 14.4 grams
TO FIND
Weight of metal A
SOLUTION
The above problem can be simply solve as follows;
Given,
Ratio of weight of Metal A to Metal B = 5:7
Let the weight of Metal A = 5x
Weight of metal B = 7x
Total weight of the alloy = 14.4 grams
Therefore,
5x + 7x = 14.4
12x = 14.4
x = 14.4/12 = 1.2
Weight of metal A = 5 × 1.2 = 6.0 grams
Hence, The answer is 6.0 grams

The ratio of metal A and metal B in an alloy is 5:7. the weight of metal A in 14.4g of the alloy is 6 grams.
Given:
the ratio of metal A and metal B in an alloy is 5:7
To find:
Weight of metal A
Solution:
A substance which is made up of two or more materials is known as an alloy.
Alloys are used because they have higher resistance of thermal conductivity than that of metals or non metals.
Let the weight of metal A = 5x
the weight of metal B = 7x
Total weight of the metal = 5x + 7x
= 12x
The weight is given as 14.4 grams.
that means, 12x = 14.4 grams
x = 14.4/12
x = 1.2 grams.
Now, weight of metal A = 5*1.2 grams
= 6.0 grams
The weight of metal A in 14.4g of the alloy is 6 grams.
