Glucose is ‘raw material’ in cellular respiration. It passes through the glycolysis cycle, in the cytoplasm of the cell. This occurs in virtually all cells. In eukaryotic cells, with mitochondria, the product of glycolysis (usually pyruvate) is channeled to the organelle and pass through the Citric acid /Krebs cycle that produces even more ATPs than glycolysis.

How many milliliters of 0.0896M LiOH are required to titrate 25.0 mL of 0.0759M HBr to the equivalence point?

slavikrds [6]

Answer:

$V_{LiOH}=21.8mL$

Explanation:

Hello,

In this case, during titration at the equivalence point, we find that the moles of the base equals the moles of the acid:

$n_{LiOH}=n_{HBr}$

That it terms of molarities and volumes we have:

$M_{LiOH}V_{LiOH}=M_{HBr}V_{HBr}$

Next, solving for the volume of lithium hydroxide we obtain:

$V_{LiOH}=\frac{M_{HBr}V_{HBr}}{M_{LiOH}} =\frac{0.0759M*25.0mL}{0.0896M} \\\\V_{LiOH}=21.8mL$

Best regards.

The answer is A.

During any chemical change the total mass doesn’t changes. Whatever the total mass of starting materials was present the same mass of ending products is present in a chemical reaction.

1.20g of methyl alcohol, CH3OH, are dissolved in 16.8g of water, H2O. What is the mole fraction of the solute?

kolezko [41]

Answer:

0.0386

Explanation:

To make a solution, we need a certain amount of the solute to be dissolved in the solvent. The solvent is the carrier medium usually water in traditional wet chemistry.

Now, in this particular question, it should be known that methyl alcohol is the solute, while water is the solvent.

We need to calculate the mole fraction of the solute as asked by the question. Now what we do is to find the number of moles of each, add together, then divide the number of moles of methyl alcohol by the sum of the moles of both.

Firstly, we calculate the number of moles of methyl alcohol present. This is mathematically equal to dividing mass by molar mass

Molar mass of methyl alcohol (CH3OH) is 12 + 4(1) + 16 = 32g/mol

The number of moles is thus 1.2/32 = 0.0375 moles

Now, we calculate the number of moles of water. The molar mass of water is 18g/mol

The number of moles of water is thus 16.8/18 = 0.93333

The mole fraction of the solute is thus:

0.0375/(0.0375 + 0.9333) = 0.0386
