Because there are parts of them just repeats them selfs over and over, classifying them as polymers.
Molar mass NaCl = 58.44 g/mol
number of moles
1 mole ------ 58.44 g
? moles ----- 25 g
25 x 1 / 58.44 => 0.4277 moles
Therefore:
M = n / V
M =0.4277 / 1.5
M = 0.285 mol/L
Answer:
The pH of an aqueous solution is the measure of how acidic or basic it is. The pH of an aqueous solution can be determined and calculated by using the concentration of hydronium ion concentration in the solution.
