Question

If the volume of one drop is 0.031 mL according to Stu Dent’s measurement, approximately what volume would 22 drops be? Answer with two significant digits and units of mL.

Answer 1

Answer:

Volume of 22 drop will be 0.68 ml

Explanation:

We have given volume of one drop = 0.031 ml

We know that 1 liter = 1000 ml

So $1ml=10^{-3}L$

So 0.031 ml will be equal to $0.031\times 10^{-3}L$

We have to find the volume of 22 drop

For finding volume of 22 drop we have to multiply volume of one drop by 22

So volume of 22 drop will be $=22\times 0.031\times 10^{-3}=0.682\times 10^{-3}L=0.68mL$

So volume of 22 drop will be 0.68 ml
