Question

Which one of the following is smallest quantity? . 0.01 g . 2 mg . 100 mg . 5000 ng

Answer 1

Answer:

Explanation:

. 100 mg

Answer 2

Answer:

5000 ng

Explanation:

let's convert every quantity to grams (g)

1) 0.01 g = 0.01 g = $10^{-2} g$

2) 0.2 mg = $0.2\times10^{-3}$ g = 0.0002 g = $2 \times 10^{-4} g$

3) 100 mg = $100\times10^{-3}$ g = 0.1 g = $10^{-1} g$

4) 5000 ng = $5000 \times10^{-9}$ g = 0.000005 g =  $5\times10^{-6} g$

Therefore, from above among all the quantities $5\times10^{-6} g$ is the smallest

i.e. 5000 ng.
