What is the mole fraction of solute in a 3.82 m aqueous solution?
To find the mole fraction of solute, you need to know the moles of solute and solvent. In this case, the moles of solute can be calculated by multiplying the molarity of the solution by the volume of the solution. Once you have the moles of solute and solvent, you can find the mole fraction of solute by dividing the moles of solute by the total moles of solute and solvent.
How many moles of solute are contained in a 250.0 ml solution with a concentration of 2.5 ml?
To calculate the moles of solute, you first need to convert the volume of the solution from milliliters to liters (250.0 ml = 0.250 L). Then you can use the formula moles = Molarity x Volume (in liters) to find the moles of solute. Given the concentration of 2.5 M, you would have 0.625 moles of solute in the solution.
What is the mole fraction of solute in a 3.62 m aqueous solution?
To find the mole fraction of solute in a solution, you need to know the total moles of both the solute and the solvent. In this case, the moles of the solute is 3.62 mol and the moles of the solvent (water) is not given. Without the moles of the solvent, the mole fraction of the solute cannot be calculated.
How to find the molarity of a solution?
To find the molarity of a solution, divide the number of moles of solute by the volume of the solution in liters. Molarity (M) moles of solute / liters of solution.
How many moles of solute are present in 1.5 liters of 1.33 M of Na2SO4?
The answer is approx. 2 moles (for anhydrous sodium sulfate).
What is the mole fraction of solute in a 3.30 m aqueous solution?
To find the mole fraction of solute, we need to know the moles of solute and moles of solvent. Here, the concentration (3.30 m) tells us the moles of solute per liter of solution, but we need more information to calculate the mole fraction. We would need the moles of solute and moles of solvent to proceed.
How many moles of solute are present in 1.25 L of a 0.75M NaNO3 solution?
To find the moles of solute, multiply the volume of the solution in liters (1.25 L) by the molarity of the solution (0.75 mol/L). Therefore, the moles of NaNO3 in 1.25 L of 0.75M solution is 0.9375 moles.
The molarity of a solution refers to?
The molarity of a solution refers to the concentration of a solute in moles per liter of solution. It is a measure of how many moles of solute are present in a given volume of the solution.
How will you determine the number of moles solute?
number of moles=solute concentration/solute molar mass
How many moles of solute are present in 1.25L of a 0.75M NaNO3?
To find the moles of solute, multiply the molarity by the volume in liters. So, (0.75 , \text{mol/L} \times 1.25 , \text{L} = 0.9375 , \text{moles of NaNO}_3).
What is the mole fraction of solute in a 3.72 m aqueous solution?
To find the mole fraction of solute in a solution, you need both the moles of solute and the total moles of solute and solvent combined. In this case, the molarity of the solution (3.72 mol/L) is not enough information to determine the mole fraction without knowing the specific solute and its moles.
How many moles of Na2CO3 are there in 10.0 L of 2.0 M soluton?
Molarity = moles of solute/Liters of solution Or, for our purposes, Moles of solute = Liters of solution * Molarity Moles Na2CO3 = 10.0 Liters * 2.0 M = 20 moles Na2CO3 --------------------------
