Answer:
Ii is the circuit overload
Explanation:
Explanation:
littoral horizantal raw curated
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
Density is defined as mass/volume (or m/v).
So,
(126.0 g)/(12.5 cm^3)= 10.08 g/cm^3
If your teacher requires correct significant figures, the answer is 10.1 g/cm^3.
If not, the first answer is fine.
