Two gold pieces, each of mass 0 . 035 g , are placed in a box of mass 2 . 3 g . The total mass of the box with gold pieces is

Options

  1. A2 . 3   g
  2. B2 . 4   g
  3. C2 . 37   g
  4. D2 . 370   g

Correct answer

B. 2 . 4   g

Step-by-step solution

( 2 .3 + 0 .035 + 0 .035 ) g = 2 . 37 g But we have to retain only one decimal place. So, the total mass is 2 . 4 g
