Answer to Question #132622 in Organic Chemistry for chris

Question

The mass of a piece of metal is 30.4571 grams. When the piece of metal was dropped into a graduated cylinder that had an initial water volume of 6.45 cm³, the total volume increased to 9.90 cm³. What is the density of the piece of metal in g/cm³?

Answer 1

solution-

Mass of piece of metal is 30.4571gm

When piece of metal was dropped into cylinder

Change in volume of water due to metal piece is equal to volume taken by metal piece

Change in volume of water = 9.90 - 6.45 cm³

= 3.45 cm³

Density of piece of metal = mass / volume

= 30.4571/3.45

= 8.8281 gm/cm³
