What is the density of an object having a mass of 5.0 g and a volume of 45.0 cm3?

Answer : The density of the object will be,

Explanation :

Density : It is defined as the mass contained per unit volume.

Formula used for density :

Given :

Mass of an object = 5.0 grams

Volume =

Now put all the given values in the above formula, we get the density of an object.

Therefore, the density of the object will be,

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
