1 Answer. Concentration = 2.5⋅mol⋅L−1 .

## What is the molarity of a solution containing 5.0 moles of HF in a 2.0 L solution?

The molarity of a solution that contains 5.0 moles of solute in 2.0 L of solution is 2.5M.

## What is the molarity of a solution that contains 5.0 moles of solute in 4.0 liters of solution?

Molarity (M)- is the molar concentration of a solution measured in moles of solute per liter of solution. The molarity definition is based on the volume of the solution, NOT the volume of water. Incorrect= The solution is 5.0 Molarity. Correct= The solution is 5.0 Molar.

## What is the molarity of a 10 L solution containing 5.0 moles of solute?

Number of moles consisting in a liter of solution is known as molarity. It is given that volume is 10 liter and there is 5.0 moles of solute. Hence, we will calculate the molarity as follows. Thus, we can conclude that molarity of the given solution is 0.5 mol/L.

## How do you find the moles of a solution?

- First you must calculate the number of moles in this solution, by rearranging the equation. No. Moles (mol) = Molarity (M) x Volume (L) = 0.5 x 2. = 1 mol.
- For NaCl, the molar mass is 58.44 g/mol. Now we can use the rearranged equation. Mass (g) = No. Moles (mol) x Molar Mass (g/mol) = 1 x 58.44. = 58.44 g.

## How would you prepare a 1 M solution of sodium hydroxide?

Popular Answers (1)

molarity = no. of moles of solute / 1 liter . * one moles of sodium hydroxide = 40 gm of sodium hydroxide. so we can said ; if want prepare 1 molar NaOH solution then we need 40 gm NaOH dissolve in one liter of water so it became one 1 molar NaOH solution.

## What is the volume of 2.00 M KCL solution?

V2 = 500.0 mL = 0.5000 L.

## How do I calculate the concentration of a solution?

The concentration of a solution can be calculated using:

- the mass of dissolved solute in grams, g.
- the volume of solution (or solvent) in cubic decimetres, dm.

## What is the concentration of a solution that contains 6 moles of solute in 2 liters of solution?

The molarity of a solution with 6 moles of solute in 2 liters is: 6 moles/2 L=3M.

## What is the molarity of a solution that contains 0.50 mole of NaOH in 0.50 liter of solution?

What is the molarity of a solution that contains 0.50 mole of NAOH in 0.50 liter of solution? 1. 1.0 M.

## How many grams of NaOH are in 500mL of a 1m solution?

Understanding math via the real world. Everything looks good except for this part: “To make one mole NaOH solution, dissolve 40 grams NaOH in 500mL of H2O.” To make a one molar solution you want to put one mole of the solute into 1L (1000mL) of H2O.

## What is the total number of moles of solute contained in 0.50 liter of 3.0 m HCL?

0.5 L of solution will contain 13. 0×0. 5=1. 5 moles of solute.

## What is the number of moles of solute in 250 mL of a 0.4 M solution?

1 Answer. There are 0.1 moles of solute in 250 mL of 0.4 M solution.

## How many moles are in a solution?

To calculate the number of moles in a solution given the molarity, we multiply the molarity by total volume of the solution in liters. How many moles of potassium chloride (KCl) are in 4.0 L of a 0.65 M solution? There are 2.6 moles of KCl in a 0.65 M solution that occupies 4.0 L.

## What is the mole formula?

Avogadro’s number is a very important relationship to remember: 1 mole = 6.022×1023 6.022 × 10 23 atoms, molecules, protons, etc. To convert from moles to atoms, multiply the molar amount by Avogadro’s number. To convert from atoms to moles, divide the atom amount by Avogadro’s number (or multiply by its reciprocal).
