Question

An alloy is made of 37% copper 31% zinc and the rest nickel. find the weight of nickel in 650 grams of the alloy ​

Answer 1

Answer:

Zinc + copper + nickel = 100%

37% + 31% + nickel% = 100%

Nickel% = 100% - 68%

Nickel% = 32%

Weight of nickel in the alloy

= 32% of 650

= 32/100 × 650

= 208gram

i hope it is correct
