Question

An alloy contain 40% copper 32% nickel and rest zinc . find the mass of zinc in one kg of The alloy

Answer 1

Answer:

Step-by-step explanation:

→ an alloy contains 40 % copper   32% nickel  

zinc = 100% -40%+32% = 28 %

mass of zinc= 28/100 = 0.28 g

Answer 2

Step-by-step explanation:

LET THE % BE X.

40+32+x=100

72+x=100

x=100-72

x=28

MASS = 1KG(GIVEN)

MASS OF ZINC = 28/100

=0.28 KG
