The 3 outside means to multiply the inside by that number. AL(NO2)3 has
1 N inside
1 x 3 = 3 nitrogen atoms
The molar mass of Al(NO3)3= 212.996 g/mol
nitrogen is 14 g/mol and is 19.7% if the molar mass
19.7% of 12 g = 2.354g
2.354/14 = 0.196 N
You should make a density trap, you get different liquids with different density's ( corn starch , water , alcohol , syrup) and pour them into a big vase and the different density's will sit on top of each other . the best thing to do is to use food coloring so that each level is a different color.
If the net forced is doubled , the acceleration would also be doubled. F= M,A,F/M = a, 2F/M=2A. sorry if that doesn’t make sense i tried
