What is the molarity of a sugar solution made from 21.0 moles of sugar with the volume of 52.0L?
The molarity of the sugar solution can be calculated using the formula: molarity = moles of solute / liters of solution. Plugging in the values, molarity = 21.0 moles / 52.0 L which equals 0.404 Molarity.
In a titration what two things are always equal to each other at the endpoint?
In a titration, the moles of the titrant added are equal to the moles of the analyte in the solution at the endpoint. This equality is essential for determining the concentration of the analyte in the solution.
What is the freezing point of 0.9 percent normal saline?
The melting point of water is lowered by 1.85 degrees Celsius if 29.2 grams of salt are dissolved in each Kg of water (called a "0.5 molal solution" of salt). So normal saline, a 0.9 molal solution), is lowered juts less thantwice this or 3.33 deg C. So normal saline freezes at -3.33 deg C or 26 deg F.
What is the formula for molarity and explain each part?
Molarity (M) is calculated as moles of solute divided by liters of solution. It represents the concentration of a solution in terms of the amount of solute dissolved in a given volume of solution. Molarity is expressed in units of moles per liter (mol/L) and is commonly used in chemistry to quantify the amount of a substance in a solution.
What is the final concentration of cl- ion when 250 ml of 0.20 M cacl2 solution is mixed with 250 ml of 0.40 M kcl solution?
To find the final concentration of Cl- ions, first calculate the moles of Cl- ions from each solution. Then add the moles of Cl- ions from both solutions and divide by the total volume of the mixed solution (500 ml) to get the final concentration. Using the formula C1V1 = C2V2 where C represents concentration and V represents volume, you can determine the moles of Cl- ions from each solution.
A solution contains 72.0 g of HCl and 468 g of (C6H6). What is the mole fraction of benzene?
First, calculate the moles of each component: moles of HCl = 72.0 g / molar mass of HCl and moles of C6H6 = 468 g / molar mass of C6H6. Then, calculate the total moles in the solution by adding the moles of each component. Finally, calculate the mole fraction of benzene by dividing the moles of C6H6 by the total moles in the solution.

Molarity of CL in 110 ml of a solution containing 5.55g of CaCl2?
To find the molarity of Cl in the solution, first calculate the number of moles of CaCl2 using its molar mass. Then, since each formula unit of CaCl2 contains 2 moles of Cl, multiply the moles of CaCl2 by 2 to get moles of Cl. Finally, divide moles of Cl by the volume of the solution in liters to find the molarity.
How many moles of H ions are present in the following aqueous solution 1410 mL of 0.32 M nitric acid?
To find the number of moles of H ions in the solution, first calculate the moles of HNO3 using the given concentration and volume. Since each mole of HNO3 yields 1 mole of H ions in solution, the number of moles of H ions is the same as the moles of HNO3. Therefore, in this case, there are 0.4512 moles of H ions present in the solution.
How many moles ok potassium are present in 343 mL of a 1.27 M solution of potassium phosphate?
To find the moles of potassium in the solution, first calculate the moles of potassium phosphate using the formula Molarity (M) = moles of solute / volume of solution in liters. Then, consider that each mole of potassium phosphate contains 3 moles of potassium ions. Finally, convert the volume of the solution to liters by dividing by 1000.
Why should each injection of IV dilantin be followed by an injection of sterile saline?
The sterile prevents venous irritation caused by the alkalinity of the solution.

What is the mole fraction of each component if 3.9g of benzene is dissolved in 4.6g of toluene?
The molar mass of benzene (C6H6) is about 78 g/mol and toluene (C7H8) is about 92 g/mol. Calculate the number of moles of benzene and toluene in the solution using the given masses. Calculate the total number of moles in the solution (benzene + toluene) and then determine the mole fraction of each component by dividing the number of moles of each component by the total moles.
