Question

please tell me the answer fast ​

Answer 1

Answer:

density = mass/volume

mass is equal to 51.1g

volume is equal to 50cm^3

density=51.5/50 => 1.03gcm^3

now,

density in kgm3= 1000× value of gcm^3

therefore value in kgm^3= 1000×1.03gcm^3=>1030kgm^3

Answer 2

Answer:

D=mass/volume

=51.5g/50cm^3 = 1.03g/cm^3

= 51.5*(10^-3)kg/50*(10^-6)m^3

(1m =100cm;1m^3=(100)^3 cm^3

= 1030kg/m^3
