The mass of a dust particle is approximately 7.5×10−107.5×10−10 kilograms and the mass of an electron is 9.1×10−319.1×10−31 kilograms. How many electrons does it take to equal the mass of a dust particle?(1 point) Responses
To find out how many electrons it takes to equal the mass of a dust particle, we can divide the mass of the dust particle by the mass of a single electron:
(7.5×10^(-10) kg) / (9.1×10^(-31) kg/electron) ≈ 8.24×10^20 electrons
Therefore, it would take approximately 8.24×10^20 electrons to equal the mass of a dust particle.
