The carnivores are the hawk, owl, and fox.
Molar mass of vitamin B1, C12H17N4OS = 265.34 g/ mol
Molar mass of vitamin B2, C17H20N4O6 = 376.37 g/ mol
Molar mass of vitamin B5, C9H17NO5 = 219.24 g/ mol
Molar mass of vitamin B6, C8H11NO3 = 169.18 g/ mol
Molar mass of vitamin B7, C10H16N2O3S = 244.31 g/ mol
Now,
Order of increasing molar mass = B6 < B5 < B7 < B1 < B2
The molality is calculated using the following rule:
molality = number of moles of solute / kg of solvent
From the periodic table:
molar mass of lithium = 6.941 gm
molar mass of chlorine = 35.453 gm
molar mass of LiCl = 6.941 + 35.453 = 42.394 gm
number of moles found in 42 gm = mass / molar mass = 42 / 42.394 = 0.99
molality = 0.99 / 3.6 = 0.275 m
Answer:
0.158 moles KMnO4
Explanation:
According to the Periodic Table,
K = 39.10 g/mol
Mn = 54.94 g/mol
O = 16.00 g/mol
KMnO4 = 39.10 g/mol + 54.94 g/mol + 4(16.00 g/mol) = 158.04 g/mol
25.0 grams KMnO4 1 mole
----------------------------- x -------------------------- = 0.158 moles KMnO4
158.04 grams
