Answer:
n = 3.3167 moles
Step-by-step explanation:
The number of mole in water
H2O
n = m/Mm
n = number of mole
m = number of mass
Mm = number of molar mass
Given :
Mass = 59.75g
Mm of H2O
H - 1.00784
O - 15.999
Mm
H = 2 * 1.00784 = 2.01568
O = 15.999
Mm of H2O = 15.999 + 2.01568
= 18.01468
insert the values into the formula
n = m/Mm
n = 59.75/18.01468
= 3.3167moles
5 because 2/6 of 24 is 8 and the difference of thirteen and 8 is 5
The standard deviation is 1, I believe...
The answer would be n=2
