What does it mean when you get a negative number like -2.28%

I understand that but how do you know which is experimental and which is theoretical

We did not graph anything. I thought % error= (expected value - experimental value) / expected value.
This is the very elementary way of doing it, i just can't remember how to determine what is what.

This may sound like a mediocre question but how do you know what the expected values and the experimental values are in an experiment? I am trying to calculate the percent error for an experiment we conducted in lab.

Thanks Everyone. For the second part, I got 154.436*4.06*11.5=7,210.617. Is this correct? This number is kind of high

Can you help me with these two questions please
If 4.436 g of NaOH was added to 150.0 mL of water and we assume the density of water to be 1.000 g/mL Then what is the total mass?
Given that the temperature change observed was 11.5 C when4.436 g of NaOH were added to 150.o mL of water, What is the heat energy in kJ that is produced. (Don't forget the specivic heat of this solution is 4.06j/g C and assume the density of water to be 1.000 g/mL)
Thanks
