A sample of metal has a mass of 16.63 g, and a volume of 7.94 mL. What is the density of this metal?

The density of the metal is 2.094 g/mL.

Explanation :

Given,

mass of metal sample = 16.63 grams

Volume = 7.94 mL.

Density = ?

Density of the metal can be found by using the formula

Density = Mass/Volume

Substituting the values we get,

density = 16.63/7.94

by solving,

density = 2.094 g/mL.

where's the diagram?

when the volume of gas is   changed from   717.73 ml   to 852 ml   the temperature will   change   from 315   c to 452   c

    calculation

this is calculated using the charles law formula

that is,   v1/t1 = v2/t2

          v1=?

        t1 = 315 c   into   kelvin = 315 +273 = 588 k

        v2 = 852   ml

        t2 = 425c + 273 =698 k

make v1   the subject of the formula ( by   multiplying both side by t1)

  v1=( v2 xt1) / t2

v1= (852 ml   x 588 k)/ 698 k= 717.73 ml
