Tom [10]

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

Find the molality of the solution if 42 grams of lithium chloride (LiCl) are dissolved in 3.6 kg of water.
omeli [17]
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

How many moles are in 25 g KMnO4
Ronch [10]

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
