A 147-g piece of metal has a density of 7.00 g/ml. 50- ml graduated cylinder contains 20.0 ml of water what is the final volume after the metal is added to the graduated cylinder

The final volume was 41

Explanation:

m = 147 grams

d = 7.00 g/mL

V = x - 20

d = m/V

7 = 147 / (x - 20)

Multiply both sides by x - 20

7*(x - 20) = 147

Divide both sides by 7

x - 20 = 147 / 7

x - 20 = 21  

Add 20 to both sides

x = 21 + 20

x = 41

The final volume was 41

b is the correct answer

mark me brainliest and hope this

i belive it is water
