Question

An alloy is made of 37%ofcoppor 31%of zinc and rast nickel.Find the weidth of nickel in 65grams of the alloy 0

Answer 1

firstly,

copper = 37%

zinc = 31%

so that the Nickel = the total mass of alloy - sum of Copper & zinc

nickel=100-(37 + 31)

nickel =100-68 = 32

so we get Nickel= 32%

now,

mass of nickel =32% ×65gm

32÷100×65 = 22.75gm.

so we get the weight of Nickel is 22.75 gram
