Answer:
0.
Explanation:
If you do a=2 and b=2, then 2-2=0.
5.00 M = 5.00 mol/L
750 mL = 0.750 L
Therefore, 5.00 mol/L x 0.750 L = 3.75 mol
Answer:Hope this helps :D
Explanation:
Cu = 27, S = 16 and O = 25.92
relative formula mass = 27 + 16 + (5.4x4.8) = 286.216
only one aluminum atom of relative atomic mass
64 % Cu = 100 x 64 / 160
x = 1036.8
