How would I answer this chemistry question?

What is the minimum volume of 0.0500 of aqueous bromine needed to react completely with 0.0200g of buta-1,3-diene (Mr - 54gmol-1)?

It is from AS paper 2 2020 AQA

The name buta-1,3-diene implies the molecule contains two alkene groups.
For each alkene group, 1 molecule of bromine is required to react with it.
Can you first calculate the moles of buta-1,3-diene in 0.0200 g and then use this to work out how many moles of bromine therefore need to react with it?

Would the moles of but-1,3-diene be 0.00037 (0.0200/54.0)
If 2 molecules of bromine are required to react with 1 molecule of buta-1,3-diene then would moles of bromine be 0.00074 (0.00037*2)
Volume of bromine= moles/conc , 0.00074/ 0.0500=0.0148 dm^3
0.0148dm^3 *1000= 14.814 cm^3 =14.8cm^3

That is exactly how you would answer it. Nicely done

Thank you, do you have any tips to avoid making silly mistakes in chemistry exam questions because sometimes I miss what the question is asking or get stuck on how to answer it during the test like with this one.

Highlight important words and information throughout the question.
Know what command words actually mean: https://www.aqa.org.uk/resources/science/as-and-a-level/chemistry-7404-7405/teach/command-words
Read the examiner’s report as well as marking past paper questions. You will find out what common mistakes are made on frequently occurring questions and how to avoid making them.
Don’t forget in structured (multiple part) calculations you may need to use answers to previous parts of the question to access later parts. If you cannot answer the earlier parts, make up answers to use in your calculations later.
