Please answer immediatelyHow many grams of glucose, C6H12O6, are needed to make 100 mL of a 1.5 M solution?

Answers

Answer 1

Answer:

THE ANSWER BOI:

27 g

HERE IS DA EXPLANATION FAM:

27 g

M(C6H12O6) = 6*12 + 12*1 + 6*16 = 180 g/mol

100 mL = 0.1 L solution

1.5 M = 1.5 mol/L

1.5 mol/L * 0.1 L = 0.15 mol C6H12O6

0.15 mol * 180 g/1 mol = 27 g C6H12O6

Answer 2

Answer:

Final answer:

To find the needed grams of glucose for a 1.5 M solution in 100ml, you multiply the molarity by the molecular weight of glucose and the volume of the solution. The calculation is 1.5 mol/l * 180 g/mol * 0.1 l = 27 grams. Therefore, 27 grams of glucose is needed.

Explanation:

The problem in question requires you to make use of the formula M= mass (mol)/ Volume (L). To find the required grams of glucose, C6H12O6, for a 1.5 M solution in 100mL, you would multiply the molarity with the molecular weight of glucose - approximately 180g per mole - and the volume of the solution - 0.1L. Therefore, to solve the problem you would calculate it as: 1.5 mol/l X 180 g/mol x 0.1 l which equals 27g. Hence, you need 27 grams of glucose to make a 100ml, 1.5M solution.

Which solution when mixed with a drop of bromthymol blue will cause the indicator to change from blue to yellow 1) 0.1 M HCl. 2) 0.1 M CH3OH. 3) 0.1 M NH3. 4) 0.1 M NaOH

Answers

The solution that when mixed with a drop of bromthymol blue will change the indicator to yellow is A. 0.1 M HCl.

What is an indicator?

An indicator simply means a substance that has measurable and observable characteristics that is important to depict an acidic or alkaline substance.

In this case, the solution that when mixed with a drop of bromthymol blue will change the indicator to yellow is 0.1 M HCl.

Answers

Another name for cytosol is cytoplasmic matrix. This is the liquid that is found in the cells. It is how the organelles are suspended within the cell.

Another name for cytosol is cytoplasmic matrix. This fluid can be found inside cells. It has to do with how the cell's organelles are held in suspension.

Numerous crucial metabolic processes occur in the cytosol, which also serves as a conduit for the movement of chemicals and ions throughout the cell. It offers a dynamic setting that supports the cellular machinery and enhances the cell's overall functionality. The term "cytoplasmic matrix" refers to the fluid-like substance (cytosol) that provides the cytoplasmic organelles and molecules with their structural support.

A sample of hydrogen gas is collected over water at 25°C. The vapor pressure of water at 25°C is 23.8 mmHg. If the total pressure is 523.8 mmHg, what is the partial pressure of the hydrogen?

Answers

The partial pressure of the gas will be the total pressure minus the vapor pressure. 523.8-23.8=500mmHg. This makes sense due to the fact that the idea of partial pressures still works even with vapor pressure since vapor pressure is just the partial pressure of water vapor (23.8mmHg) in the container which is added to the partial pressure of hydrogen gas (500mmHg) to make a total pressure of 523.8mmHg.
