Today I've made the most stupid thing in the world!!!

As I soon finish my practical and write my reports, I have to weigh the sample bag, put my paracetamol (I've made it during practical) and re-weigh it.

So I follow the steps and I have to calculate the % yield of products, which is the mass of sample I have (actual yield) divide by the mass that suppose to have (theoretical yield) and multiply it by 100%.

So I calculate it and write my conclusion and I hand in my reports to the demonstrator.

After 3 hours, I just realise I made a mistake in the calculation.

The actual yield of sample is the mass of paracetamol, BUT INSTEAD I WROTE THE MASS OF PARACETAMOL INCLUDING THE MASS OF THE SAMPLE BAG!!!!!

OMG I'M SO STUPID!!!!!!
