Question

The mass of a ball is 175 g. What should be its volume to have a density of 0.700 g cm-3 ? Also find its density in S.I units and its relative density. explain​

Answer 1

Explanation:

The density of a cube is measured by measuring its mass and the length of its side. If the maximum errors in the measurement of mass and length are 4% and 3% respectively, the maximum erfor in the measurement of the density is - (A) 9% (C) 12% (B) 13% (D) 7%

Answer 2

Given Data:

                 mass=175g

                 density=0.700g cm^{-3}

To find:

            its density in SI units

solution:

           ∴ $Volume=\frac{Mass}{Density}$

              $v=\frac{175}{0.700}$

to take the decimal point out,

     ∴$\frac{1}{1000}=0.001$

     ∴$0.001X1000=1$

      $v=\frac{175X1000}{0.700X1000}$

      $v=\frac{175000}{700} \\\\v=250cm^{-3}$

∴The volume of the ball is $250cm^{-3}$
