Best way to determine the weight/volume of a grain of sand/salt

AI Thread Summary
To determine the weight and volume of a grain of salt or sand, one approach is to count and weigh 100 grains, then calculate the average weight. The water displacement method can be used to measure the volume of the same 100 grains. There is a suggestion that the teacher is more focused on the methodology rather than the results of the lab. The proposed methods align with common practices in similar experiments. Overall, gathering diverse ideas for this lab is encouraged.

I'm not looking into anyone giving me any answers here, but I just want to gather some ideas for a lab that requires me to calculate the volume and wieght (therefore, finding the density) of a grain of salt and sand.

I've thought about the idea of counting out 100 grains and then weighing them, then dividing it by 100 for weight. And to use a water displacement method to find the volume, again using 100 grains of salt.

Does anyone have any other possible ideas?

Any advice, input, and thoughts, would we well recieved.

Thanks,

Jason

P.S. - My teacher says that is a lab that will not work effectively. The teacher is more interested in finding out how I do the lab, not my lab results.

Your method sounds like the way most people would do it.
 
I multiplied the values first without the error limit. Got 19.38. rounded it off to 2 significant figures since the given data has 2 significant figures. So = 19. For error I used the above formula. It comes out about 1.48. Now my question is. Should I write the answer as 19±1.5 (rounding 1.48 to 2 significant figures) OR should I write it as 19±1. So in short, should the error have same number of significant figures as the mean value or should it have the same number of decimal places as...

Figure 1 Overall Structure Diagram Figure 2: Top view of the piston when it is cylindrical A circular opening is created at a height of 5 meters above the water surface. Inside this opening is a sleeve-type piston with a cross-sectional area of 1 square meter. The piston is pulled to the right at a constant speed. The pulling force is(Figure 2): F = ρshg = 1000 × 1 × 5 × 10 = 50,000 N. Figure 3: Modifying the structure to incorporate a fixed internal piston When I modify the piston...
Thread 'A cylinder connected to a hanging mass'
Let's declare that for the cylinder, mass = M = 10 kg Radius = R = 4 m For the wall and the floor, Friction coeff = ##\mu## = 0.5 For the hanging mass, mass = m = 11 kg First, we divide the force according to their respective plane (x and y thing, correct me if I'm wrong) and according to which, cylinder or the hanging mass, they're working on. Force on the hanging mass $$mg - T = ma$$ Force(Cylinder) on y $$N_f + f_w - Mg = 0$$ Force(Cylinder) on x $$T + f_f - N_w = Ma$$ There's also...
