Question

f an electron has a mass of 9.709 x 10-31 kg, and a proton has a mass of 1.672 x 10-27 kg, approximately how many electrons are required to have the same mass as one proton?

Answer 1

The answer is 1722 e⁻

Step-by-step explanation:

Let's make a rule of three:

9.708×10⁻³¹ kg is the mass of 1 e⁻

1.672 ×10⁻²⁷ kg (which is 1 p⁺), how many e⁻ does it contain.?

1.672 ×10⁻²⁷ kg / 9.708×10⁻³¹ kg

The answer is 1722 e⁻
