Un échantillon de nickel a une masse de 63,25 g et occupe un Volume de 7,0 cm. Quelle est sa masse volumique?

A sample of nickel has a mass of 63.25 g and occupies a volume of 7.0 cm. What is its density?

9.04g/cm³

Explanation:

Given parameters:

Mass of nickel = 63.25g

Volume of the nickel  = 7.0cm³

Unknown:

Density of the nickel = ?

Solution:

Density is a physical quantity. It is an intensive property of matter because all samples of given matter will have distinct density value.

  Density is the mass per unit volume of a substance;

       Density  =  

Insert the parameters and solve;

    Density  =   = 9.04g/cm³

93.2 ml + 3920 ml = 4013 ml total  

(93.2 ml) * (2.03 m) / (4013 ml) = 0.0471 m

the volume in in l of the diluted solution would be 0.0471 m.
