how many moles of potassium dichromate (k2cr2o7) are required to prepare a 250-ml solution of with a concentration of 2.16 m?

Eva8 [605]

The moles of potassium dichromate , K₂Cr₂O₇ are required to prepare a 250 mL solution of with a concentration of 2.16 M is 0.54 mol.

given that :

molarity = 2.16 M

volume = 250 mL = 0.25 L

the molarity is given as :

molarity = number of moles / volumes in L

from this we can calculate the number of moles, we get :

number of moles of K₂Cr₂O₇ = molarity × volume

number of moles of K₂Cr₂O₇ = 2.16 × 0.25

number of moles of K₂Cr₂O₇ = 0.54 mol

Thus, The moles of potassium dichromate , K₂Cr₂O₇ are required to prepare a 250 mL solution of with a concentration of 2.16 M is 0.54 mol.

Yeast and other organisms can convert glucose (C6H12O6) to Ethanol (CH3CH2OH) through a process called Alcoholic Fermentation. T

Murljashka [212]

Answer:

The answer to your question is 8.28 g of glucose

Explanation:

Data

Glucose (C₆H₁₂O₆) = ?

Ethanol (CH₃CH₂OH)

Carbon dioxide (CO₂) = 2.25 l

Pressure = 1 atm

T = 295°K

Reaction

C₆H₁₂O₆ ⇒ 2C₂H₅OH(l) +2CO₂(g)

- Calculate the number of moles

PV = nRT

Solve for n

$n = \frac{PV}{RT}$

Substitution

$n = \frac{(1)(2.25)}{(0.082)(295)}$

Simplification

n = 0.092

- Calculate the mass of glucose

1 mol of glucose --------------- 2 moles of carbon dioxide

x --------------- 0.092 moles

x = (0.092 x 1) / 2

x = 0.046 moles of glucose

Molecular weight of glucose = 180 g

180 g of glucose --------------- 1 mol

x g ---------------0.046 moles

x = (0.046 x 180) / 1

x = 8.28 g of glucose
