Question

question 5
there are 100 microliters (ul) in a milliliter (ml).
a true
b false

Explanation:

Step1: Unit conversion relationship

We know that \(1\space mL = 10^{- 3}\space L\) and \(1\space\mu L=10^{-6}\space L\).
Let's find the relationship between \(mL\) and \(\mu L\). Let \(x\) be the number of \(\mu L\) in \(1\space mL\).
We set up the proportion \(\frac{x\space\mu L}{1\space mL}=\frac{10^{-6}\space L}{10^{-3}\space L}\) (since \(1\space\mu L = 10^{-6}\space L\) and \(1\space mL=10^{-3}\space L\)).

Step2: Solve the proportion

Cross - multiply: \(x\times10^{-3}=1\times10^{-6}\). Then \(x = \frac{10^{-6}}{10^{-3}}\).
Using the rule of exponents \(a^{m}/a^{n}=a^{m - n}\), we have \(x = 10^{-6+3}=10^{3}=1000\).

Answer:

B. False
