Question

An alloy contains 40% Cooper, 32% nicle and rest zinc. find the mass of zinc in one kg of alloy .​

Answer 1

Answer:

280 gram

Step-by-step explanation:

An alloy contains -

40% Cooper

32% nicle and

rest zinc

Total mass taken by both copper and nickle = 40% + 32% = 72%

mass of rest of zinc = 28%

mass of zinc = 28/100 × 1000g

= 280 gram

= 0.28 kg

Answer 2

Answer:

Copper contains = 40%

Nickel contains = 32%

The sum of Copper and Nickel = 40% + 32% = 72%

Mass of Zinc = 100% - 72% = 28%.

Therefore , mass of Zinc contains 28%.
