A person measures mass of 3 different particles as 435.42 ~g , 226.3 ~g and 0.125 g. According to the rules for arithmetic operations with significant figures, the additions of the masses of 3 particles will be.

Options

  1. A661.845 g
  2. B662 g
  3. C661.8 g
  4. D661.84 g

Correct answer

C. 661.8 g

Step-by-step solution

m ₁+ m ₂+ m ₃=435.42+226.3+0.125 According to least significant digits m =661.8 ~g
