How many atoms does 2 HCl have?
Explanation: One mole of anything is 6.022×1023 of anything, including molecules. Every HCl molecule contains two atoms, H and Cl.Shahrivar 15, 1396 AP
What is a 1 molal solution?
Answer and Explanation: A 1 molal solution is one mole of a given substance dissolved in 1 kg of solvent. For example, if we are dissolving water into methanol then water would be the solute and methanol would be the solvent.
How do you make a 1 molal solution?
A one molal solution contains 1 mole of solute per 1000 g (1 kg) of solvent. To prepare a one molal solution of sucrose you would weigh one mole of sucrose into a container and add 1000 g water (1 liter). Note that volume of solvent rather than the volume of solution is measured.
Which has more concentration 1 molar or 1 Molal?
1 molar aqueous solution is more concentrated than 1 molal aqueous solution because 1 molar solution contain 1 mole of solute in 1 litre of the solution which include both solute and solvent. So, the mass of solvent (i.e. water) is less than 1000 gram. Hence concentration will be more in 1 molar aqueous solution.Farvardin 11, 1391 AP
Which has higher concentration 1M or 1M?
In 1 molar solution, 1 mole of solute is in 1 litre of solution That means solute and solvent makes 1 litre. While in 1 molal solution 1 mole of solute is dissolved in 1 litre of solvent. So 1 molar solution is more concentrated than 1 molal solution.Tir 12, 1398 AP
Why is a one molal solution easier to prepare than a one molar solution?
Compared to molar concentration or mass concentration, the preparation of a solution of a given molality is easy because it requires only a good scale; both solvent and solute are massed, rather than measured by volume.
What is the difference between a 1 M solution and a 1 M solution?
Molarity is defined as the number of moles of solute in exactly 1 liter (1 L) of the solution. If one mole of solute is dissolved in 1 liter of solution, then the molarity of the solution is said to be 1M. If one mole of solute is dissolved in 1 kg of solvent, then the molality of solution is said to be 1 m.
Why do we prefer Molality over molarity and normality?
Molarity is number of moles per unit volume of the solution and molality is number of moles per unit mass of solvent. Volume is temperature dependent where as mass is constant at all temperatures. So, molality remains constant but molarity changes with temperature. Hence , molality is preferred over molarity.Farvardin 5, 1396 AP
Which salt solution is most concentrated?
Which salt solution is more concentrated, solution A, which contains 24 g of salt in 12 L of water? Explain. Salt solution A contains a concentration of 3 g/L, whereas salt solution B contains 2 g/L. Therefore, solution A is more concentrated than solution B.
Who is the most concentrated level 202?
Answer: Drag the scissors to the balloon to pop it, then tap on the lamp to find the most concentrated.Aban 13, 1399 AP
What is the distinction between a suspension and solution?
The difference between a solution and a suspension is in the particle sizes involved. A solution is a mixture of ions or molecules (very, very small). Solutions are transparent, meaning that you can see through them. A suspension has bigger particle sizes and so it may look cloudy or murky.Bahman 13, 1382 AP
Which solution is the most concentrated 0.1 mole?
From the given solutions most concentrated solution is 4th solution. In this the highest amount of solute dissolved in a unit volume is 4.0 mol. Therefore this is the most concentrated solution….
- 0.1 mol/ 0.4 L = 0.25 mol/L.
- 0.2 mol / 0.3 L = 0.67 mol/L.
- 0.3 mol / 0.2 L = 1.5 mol/L.
- 0.4 mol/ 0.1 L = 4.0 mol/L.
