Question

hello everyone
An alloy contains 40%copper, 32% nickel and rest zinc. Find the mass of zinc in one kg of the alloy
Please answer the question fast ​

Answer 1

Answer:

percentage of copper in the alloy = 40%

percentage of nickel in the alloy = 32%

∴ percentage of zinc in the alloy = 100% -(40% + 32%)

                                                      = 100% - 72%

                                                      = 28%

Then the mass of zinc in one kg of alloy = 1 kg x 28%

                                                                   = (1000 x 28)/100 gm

                                                                   = 280 gm

∴ Mass of zinc in one kg of the alloy = 280 gm
