Question

mass=?,volume=190,density=4

Answer 1

density= mass÷volume
mass=density×volume
mass =4×190
mass=760
hope it will help u

Answer 2

" Density "

Density is defined as mass per unit volume.

Here we have,
m = ?
v= 190
density = 4

so if density = m / v
=> 4 = m / 190
=> m = 190 x 4
=> m = 760 kg

Hence, required mass is of 760 kg of can be 760 g.
