A person measures mass of 3 different particles as 435.42 g,226.3 g435.42 \mathrm{~g}, 226.3 \mathrm{~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

m1+m2+m3=435.42+226.3+0.125\mathrm{m}_1+\mathrm{m}_2+\mathrm{m}_3=435.42+226.3+0.125
According to least significant digits m=661.8 g\mathrm{m}=661.8 \mathrm{~g}
