Question

A typical aspirin has a mass of 500mg. How do you convert this quantity to grams?

Answer 1

Hint: So to solve the above type of question we should know how many milligrams is required to make it to one gram and then use it to find the amount of grams which will then represent the amount of milligrams which is stated in the above question.

Complete step-by-step solution:
We all know that one gram is one thousand milligram,
As the name milligram signifies i.e. milli which is one thousand parts of a substance from which we derived that one-thousand milligrams combines to form one gram of substance.
In the above question, which is given, it is stated that we have aspirin which has a mass of five hundred mg (milligrams), now so as to convert that amount of milligrams we will have to divide given amount in milligrams by one thousand as we know that one milligram is one thousand part of one gram.
So now to find out the mass of aspirin which is stated as 500 milligram, in grams we divide the mass of aspirin stated in the question by one thousand and the result we got is as stated below:
\[\begin{align}
  & \text{mass of aspirin in grams(g) = }\left( \dfrac{500}{1000} \right) \\
 & \Rightarrow \text{mass of aspirin in grams(g) = }\dfrac{1}{2}\text{g} \\
\end{align}\]
Now from the calculation that we can see above, we can clearly say that the amount of aspirin that was stated by the question as 500 mg is equivalent to\[\dfrac{1}{2}\text{g}\].

Note: In the type of questions that has been mentioned as above we should always remember the conversion value i.e. like in the above question we can see that the conversion value of one gram to one milligram is one thousand i.e. one gram is equivalent to one thousand milligram i.e. 1g = 1000mg.
