What is the molarity of 10 moles of salt dissolved in 20 liters of water?
The molarity of the salt solution can be calculated by dividing the number of moles of solute (salt) by the volume of solution in liters. In this case, the molarity would be 10 moles / 20 liters = 0.5 moles per liter (M).
What is a example of concentration involving volume and mass?
1 molar NaCl is 58.5 g of salt ( a mass) per liter (a volume).
Of you have 5 moles of salt make 5 liters of solution what will be the molarity of the solution?
To calculate molarity, you need to know the moles of solute and the volume of solution in liters. In this case, you have 5 moles of salt in 5 liters of solution, so the molarity would be 1 M (5 moles ÷ 5 liters = 1 M).
What is an example of a solution for science?
An example of a solution in science is a mixture of salt and water. In this case, the salt dissolves in the water, resulting in a clear and uniform solution. This solution can then be separated back into its individual components through methods like evaporation.
How many grams of salt must be dissolved in water to make 2 liters of a 2M solution?
To determine the number of grams of salt needed to make a 2M solution in 2 liters of water, we first need to calculate the molar mass of salt. For example, if we are using NaCl (table salt) with a molar mass of 58.44 g/mol, we can calculate the grams of salt needed using the formula: molarity (M) = moles (mol) / volume (L). Therefore, for a 2M solution in 2 liters, you would need 2 moles of salt. Multiplying the moles by the molar mass gives us 116.88 grams of salt required.
How many salt is in a salt solution?
The salt content of a salt solution can be found from the solutions' molarity. Any solution with a salt content can be called a salt solution. There is no one set standard which determines the amount of salt which must be in a solution for it to be a salt solution.
What volume (in milliliters) of a 0.150 M salt water solution contains 0.500 g of NaCl?
To find the volume of the solution containing 0.500 g of NaCl, first, calculate the moles of NaCl using its molar mass (58.44 g/mol). Then use the molarity formula (Molarity = moles/volume) to find the volume. The volume of a 0.150 M solution that contains 0.500 g of NaCl would be approximately 8.5 ml.
What is the solution in salt with water?
Salt is the solute. Water is the solvent. Salt water is the solution. This solution is sometimes called a saline solution.
Is salt water mixture or solution?
Salt water is a solution of salt dissolved in water.
Potassium fluoride (KF) a salt has a molecular weight of 58.10 grams. How many grams would be needed to mix 1.0 liter of 0.10 M salt solution?
To calculate the grams needed to mix a 0.10 M potassium fluoride solution, you would first find the molar mass of KF (58.10 g/mol). Then use the formula Molarity = moles/Liter to find the moles of KF needed (moles = Molarity x Volume). Finally, convert moles to grams using the molar mass: grams = moles x molar mass. In this case, you would need 5.81 grams of KF to make a 0.10 M solution in 1.0 liter.
What is salt in salt solution?
Salt is the solute. Water is the solvent. Salt water is the solution. This solution is sometimes called a saline solution.
How can a chemist accurately prepare a solution of precise molarity?
A chemist's preparation of a precise molar solution is based upon the following criteria. First, the substance being solvated must be of known purity and precise mass. Accordingly the chemist's mass instrumentation must be correctly calibrated and zeroed. Second, the volume of water needs to be precisely measured to ensure the molar yield is reached. Third, the solution must be thoroughly (and possibly actively) mixed to ensure equal molar concentration throughout the solution.
