Question

The ratio of Weights of tin and zinc is in alloy is 2: 5. How much zinc is there in 31. 5 g of alloy

Answer 1

Answer:

22.5g

Step-by-step explanation:

the ratio of weights of tin and zinc is given as 2:5

let weight of tin be 2x,weight of zinc=5x

given total weight of alloy =31.5g

so 2x+5x=31.5

7x=31.5

x=31.5/7

x=4.5

weight of tin =2x=2×4.5=9g

weight of zinc=5x=5×4.5=22.5g

THEREFORE YOUR ANSWER IS 22.5g.

I hope you are satisfied by my answer.
