I need help figuring out the calculations of my experiment. I'm sure I did something wrong cause I can not figure how to calculate the mass of sodium chloride. My measurements follow.
1. 250 mL beaker = 8.4
2. Mass of container = 0.4013
3. mass of container + sodium chloride = 5.4013
4. mass of sodium chloride (show calculation setup)_____________
I subtracted .4013 from 5.0143 and got 5. but somehow I don't think this is correct. I NEED HELP
Thanking you in advance

If things are what you show then mass NaCl is 5.0000 and the extra zeros are necessary to show the number of significant figures. There is no indication for the use of the 8.4 nor the units.
