Question

How to convert \[300mL/hr\] to \[ML/min\]?

Answer 1

Hint:
In the given question, we have been given a quantity in one unit of measurement which is to be converted to another unit of measurement. To do that, we are first going to convert \[mL\] to \[ML\]. Then we are going to convert hours to minutes. Then we are going to simplify and that gives us the answer.

Formula Used:
We are going to use following units of measurement:
\[1mL = \dfrac{1}{{{{10}^6}}}ML\]
\[1hr = 60\min \]

Complete step by step solution:
We are given to convert \[300mL/hr\] to \[ML/min\].
First, we are going to convert \[mL\] to \[ML\].
We know, \[1mL = \dfrac{1}{{{{10}^6}}}ML\].
Hence, \[300mL/hr = \dfrac{{300}}{{{{10}^6}}}ML/hr = \dfrac{3}{{{{10}^4}}}ML/hr\]
Now, we are going to convert hours to minutes.
Now, \[1hr = 60\min \],
Hence, \[\dfrac{3}{{{{10}^4}}}ML/hr = \dfrac{3}{{{{10}^4}}} \times \dfrac{1}{{60}}ML/\min = \dfrac{1}{{2 \times {{10}^5}}}ML/\min \]
or,
\[ = 5 \times {10^{ - 6}}ML/\min \]

Note:
In the given question, we had been given a quantity in one unit of measurement which was to be converted to another unit of measurement. To do that, we first converted mL to ML. Then we converted hours to minutes. Then we simplified the expression and that gave us the answer.
