Nocturnal animals, such as owls, tend to have wide pupils and several rod cells in their retina because wide pupil allow more light to enter the eyes and the rods cells in the retina are sensitive to dim light and are vital for night vision.
D) The movement of electrons between atoms
Answer:
a) 0.5198 mol/L
b) 0.00811 mol KOH
Explanation:
a) M(KOH) = 39+16+1= 56 g/mol
14.555g* 1 mol/56 g = 14.555/56 mol KOH in 500.0 mL solution
14.555/56 mol KOH ---- 0.5000 L solution
x mol KOH ----- 1 L solution
x = (14.555/56)mol * 1L/0.5000 L = 0.5198 mol/L
b) If the student pours out a 15.6 mL sample of this solution, how many moles of sodium hydroxide? (if we talk about KOH)
does the student have in the sample
15.6 mL = 0.0156 L
0.5198 mol/L * 0.0156 L = 0.00811 mol KOH
