How may grams of KNO3 should be used to prepare a 2.0L of a 0.50 M solution?
Get moles by; Molarity = moles of solute/Liters of solution 0.50 M KNO3 = moles KNO3/2.0 L = 1.0 mole KNO3 Now find grams of 1.0 mole KNO3 1.0 mole KNO3 (101.11 grams/1 mole KNO3) = 101.11 grams KNO3 needed call it 100 grams
How many atoms are in 3 moles of potassium nitrate?
To calculate the number of atoms in 3 moles of potassium nitrate (KNO3), you use Avogadro's number, which is 6.022 x 10^23 atoms/mol. First, calculate the molar mass of KNO3 (101.1 g/mol) then multiply that by 3 to get the total mass in grams. Next, divide the total mass by the molar mass to get the number of moles, and finally multiply the number of moles by Avogadro's number to get the number of atoms. For 3 moles of KNO3, there are approximately 5.4 x 10^24 atoms.
If you have 10.0 g each of Na C Pb and Ne which contains the largest number of moles?
To determine which substance contains the largest number of moles, you need to divide the given mass of each substance by its molar mass to find the number of moles. The substance with the largest number of moles will have the smallest molar mass. In this case, Neon (Ne) has the smallest molar mass, so it contains the largest number of moles.
How can one determine the molar mass from molality?
To determine the molar mass from molality, you can use the formula: Molar mass (molality x molar mass of solvent) / molality of solute. This equation helps you calculate the molar mass of a substance based on its molality in a solution.
How do you find the percent of oxygen by mass in a compound?
To find the percent of oxygen by mass in a compound, you need to know the molar mass of the compound and the molar mass of oxygen. Divide the molar mass of oxygen by the molar mass of the compound and multiply by 100 to get the percentage.
What is the mass for potassium nitrate?
Molar mass of KNO3 is 101gmol-1. This is a neutral compound.
How many moles of KNO3 are in 6.5 grams?
The molecular weight of potassium nitrate (KNO3) is 101.1 grams/mole.K = 39.1 + N = 14.0 + O = 3*16.0 = 101.1Now divide 6.5 by 101.1 to calculate # of moles => 0.064 moles KNO3

What is gram formula mass of KNO3?
Mass of KNO3 K = 1 * 39.10 g = 39.10 g N = 1 * 14.01 g = 14.01 g O = 3 * 16.00 g = 48.00 g Total = 101.11 g The molar mass of potassium nitrate is 101.11 grams.
What is the molarity of a solution that contains 5.10 mol KNO3 in 4.47 kg?
First, convert the mass of KNO3 from kg to g (1 kg = 1000 g). 4.47 kg = 4470 g. Next, calculate the molarity using the formula Molarity = moles of solute / volume of solution in liters. Given that the moles of KNO3 is 5.10 mol and the mass of KNO3 is 4470 g, you need to convert the mass to volume using the density of KNO3 to determine the volume of solution in liters.
