A sample of 76g of NaCl is dissolved to make 1L of solution. what is the molarity of the solution?
1.3g
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).
Why doesn't adding one mole of solute to one liter of water make a one molarity solution?
molarity of moles of solute/liters of solution(not solvent) the volume of the solvent(even if it started at 1 L) would change after adding the solute depending on the molar mass, density, etc of the solute, the molarity would be different
18.6 grams of a solute with molecular mass of 8940 grams are dissolved in enough water to make 1.00 dm of solution at 25 àC What is the osmotic pressure of the solution?
Using the formula for osmotic pressure π = iMRT, where i is the van't Hoff factor, M is the molarity in mol/L, R is the gas constant, and T is the temperature in Kelvin, we can calculate the osmotic pressure. First, determine the number of moles of solute in the solution using the given mass and molecular mass. Then calculate the molarity of the solution. Finally, plug in the values and solve for the osmotic pressure.

How do you calculate molarity of substance?
Molarity is calculated by dividing the moles of solute by the liters of solution. The formula is: Molarity (M) = moles of solute / liters of solution. This is a common way to express the concentration of a solution.
How many grams of sodium sulfate Na's must be added to make 500 ml of M sodium sulfate solution?
To determine the grams of sodium sulfate needed, you first need to specify the molarity (M) of the sodium sulfate solution. Once you have the molarity, you can use the formula: grams = molarity (M) x volume (L) x molar mass (g/mol). This will give you the amount of sodium sulfate in grams needed to make the solution.
How do you make a Molar solution from 32 percent hydrochloric acid?
To make a molar solution from a 32% hydrochloric acid solution, you would need to first calculate the molarity of the 32% solution. Molarity is calculated by multiplying the percent concentration by the density of the solution and dividing by the molar mass of the solute. Once you determine the molarity, you can then dilute the solution to the desired molar concentration by adding the appropriate amount of solvent (usually water).
What is the molarity of a solution made by dissolving 23.4g of sodium sulphate in enough water to make up a 125ml solution?
To find the molarity, first calculate the number of moles of sodium sulphate using its molar mass. Sodium sulphate's molar mass is 142.04 g/mol. Next, divide the number of moles by the volume in liters (125 ml = 0.125 L) to get the molarity. This will give you the molarity of the sodium sulphate solution.
Molarity of 734 grams of lithium sulfate are dissolved to make 2500ml of solution?
To find the molarity of the solution, first calculate the number of moles of lithium sulfate in 734g. Then, divide the moles by the volume of solution in liters to get the molarity. Remember to convert grams to moles using the molar mass of lithium sulfate (Li2SO4).
What is the molarity of a solution made by dissolving 3.09 moles of Nacl in 1.50 L of solution?
what is the molarity of a solution prepared by dissolving 36.0g of NaOH in enough water to make 1.50 liter of solution?
If 3.0 mol of CaCl2 are added to water to make 0.500L of solution what is the concentration in molarity?
molarity is #moles divide by # liters, so 3.0 divided by 0.500 is 6.0 molarity (2 siginficant figures is all you are allowed)
Why is molarity important in chemistry?
The molar volume equals 22.4 L and containing 6.02x10^23 (Avogadro's Number) molecular or atomic particles at standard temperature (273.15 K) and pressure (1 ATM), also knows as STP. This allows scientists to use the Ideal Gas Law of PV= nrt. Pressure (P), volume (V), moles (n), the radial gas law constant (r), and temperature. Using the molar volume and the Ideal Gas Law together allow them to determine how much space a certain number moles occupy dependent on temperature and pressure.
If 2.0 mL of 6.0M HCl is used to make a 500.0-mL aqueous solution what is the molarity of the dilute solution?
The number of moles of HCl in the initial solution can be calculated using the formula M1V1 = M2V2, where M1 = 6.0 M, V1 = 2.0 mL, V2 = 500.0 mL, and M2 is the unknown molarity. Solving for M2 gives a molarity of 0.024 M for the dilute solution.
What is the molarity of the solution containing 5.0 moles of KCl in 2.0 L of solution?
Molarity is moles per litre. So you have to convert volume to a litre. i.e. 0.5x2 is a litre. so you have to do the same to moles. 5x2 is 10 moles. as this is per litre, it is a 10 molar solution.
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).
