How many moles are in AgNO3?
you find moles of AgNO3. That is 0.0132 g AgNO3 x 1 mol AgNO3/169.9 g = 7.77×10-5 moles. Since there is 1 mole Ag and 1 mole NO3 per mole of AgNO3, this is also the number of moles of Ag+ and NO3- ions.
Can you convert grams to moles?
Divide the number of grams of the compound, NaOH, by the molecular weight and as a result, the grams (g) unit cancels and all we have left is the unit mol (moles).
How do you find the moles given the grams?
Divide the mass of the substance in grams by its molecular weight. This will give you the number of moles of that substance that are in the specified mass.
How many moles are in 2.58 g of silver nitrate?
1 Expert Answer
1) (2.58 g AgNO3) * (1 mole AgNO3 / 169.9 g AgNO3) = 0.0152 mole AgNO3.
How do you find moles from molarity?
To calculate the number of moles in a solution given the molarity, we multiply the molarity by total volume of the solution in liters.
Why is a mole 6.02 x10 23?
Originally, a mole was the quantity of anything that has the same number of particles found in 12.000 grams of carbon-12. That number of particles is Avogadro’s Number, which is roughly 6.02×1023.
What is the formula for calculating moles?
Divide the number of grams of each reactant by the number of grams per mole for that reactant. 50.0 g of Na are used in this reaction, and there are 22.990 g/mol. 50.0 ÷ 22.990 = 2.1749. 2.1749 moles of Na are used in this reaction.
How many moles are in 22 grams of argon?
number of moles of Ar = 22 g / 40 g/mol = 0.55 mol .
