What is the total number of moles of solute contained in 0 50 liter of 3 0 m HCL?

What is the molarity of a solution that contains 20 grams of CaBr2 in 0.50 liter of solution?

What is the number of grams of KCl in 1,00 liters of a 0.200 molar solution? What is the molarity of a solution that contains 20 grams of CaBr2 in 0.50 liter of solution? 3. 0.25 M 4.0.

How do you calculate moles per liter?

As mass / volume = molarity * molar mass , then mass / (volume * molar mass) = molarity . Substitute the known values to calculate the molarity: molarity = 5 / (1.2 * 36.46) = 0.114 mol/l = 0.114 M . You can also use this molarity calculator to find the mass concentration or molar mass.

How do you find moles of solute?

One mole equals the molar mass of the solute which is 58.4538 grams. Divide the mass of the solute by the molar mass to get the number of moles of solute. In this case, work out 200 ÷ 58 = 3.4483 moles of solute.

What is the molarity of a 0.30 liter solution containing 0.50 moles of nacl?

concentration=[NaCl(aq)]=0.50⋅mol0.30⋅L=1.67⋅mol⋅L−1 .

How many liters of a 0.2 m NaOH solution would contain 0.4 mole of NaOH?

5 litres of solution are required.

How many moles are in 40 grams of NaOH?

Now take 120 grams NaOh and multiply this by 1 mol NaOH/ 40 grams NaOH. You can cancel out the grams and you have moles left. Now you do 120 x 1 / 40 and you get 3 moles of NaOH!

How is mol calculated?

  1. 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.
  2. 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 many moles of AgNO3 are present in 1.50 L?

Answer Expert Verified

So 0.075 moles of AgNO3 are present in 1.50 L of a 0.050 M solution.

How do you find how many grams are in a mole?

Divide the mass of the substance in grams by its molecular weight. This will give you the number of moles of that substance that are in the specified mass. For 12 g of water, (25 g)/(18.015 g/mol) = 0.666 moles.

Can you have negative moles?

mol have a negative 1 (g. mol^ Answer: means the same as g/mol. The negative 1 exponent is just a mathematical way to describe a quantity that is divided by some other one.

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

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

What is the molarity of a 1.5 liter solution prepared using 4.6 grams of HCl?

Molarity of HCl = 0.084 M

What is the molarity of a 1.5 liter solution prepared using 4.6 grams of HCI? Link copied!

What volume of a 0.55 M solution can be made using 0.25 moles of Ca Oh 2?

Explanation: 0.25 M means 0.25 moles of KCl in 1 liter. 0.50 moles is twice that amount of moles, so it can make twice the amount of solution, so it makes 2 liters.

How many moles of solute would 3 liters of a 2 molar solution contain?

If it was 3 mol of solute in 2 L of solution it would be 1.5 mol/L.
