Question

The mass of a length of metal wire is 45 g. When the wire is placed in a graduated

Answer 1

Answer:

The answer to your question is 9 g/ml or 9 g/cm³

Explanation:

Data

mass = 45 g

volume = 5 ml

density = ?

Process

1.- Consider that the volume displaced is equal to the volume of the wire.

2.- Write the formula to calculate the density

density = mass/volume

3.- Substitution

density = 45/5

consider milliliters and cubic centimeters are the same.

4.- Result

density = 9 g/ml or 9 g/cm³  

Answer 2

5 ml=5 cm³ , density=mass/volume=45/5= 9 g/cm³ therefore answer B
