An electron’s mass is approximately 9.1093826 × 10⁻³¹ kilograms. What is this mass in grams?

Solution:

Given, an electron’s mass is approximately 9.1093826 × 10⁻³¹ kilograms.

We have to express the mass in grams.

We know, 1 kg = 1000 gm

So, 9.1093826 × 10⁻³¹ kilograms = 9.1093826 × 10⁻³¹ × 1000

= 9.1093826 × 10⁻³¹ × 10³

Using law of exponents,

a^m × aⁿ = a^{m + n}

= 9.1093826 × 10⁻^{-31 + 3}

= 9.1093826 × 10⁻²⁸ gm

Therefore, the required mass in grams is 9.1093826 × 10⁻²⁸ gm
