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.
How do you calculate moles of silver?
The molar mass of silver is 107.9 g/mol. Therefore: n moles of silver atoms will have a mass of (n TIMES 107.9) g. The problem says: 6.89 g EQUALS (n TIMES 107.9) g; so we solve for n by dividing 6.89 by the molar mass (107.9). This (n) gives us the mole count.
How do you calculate 1 mole of AgNO3?
So in order to calculate the number of moles of any substance present in the sample, we simply divide the given weight of the substance by its molar mass. Where ‘n’ is the number of moles, ‘m’ is the given mass and ‘M’ is the molar mass.
How many moles is each of the following 79.3 g Cl2?
The gram molecular mass of Cl2 is 70.906, twice the atomic mass of chlorine atoms. Therefore, 79.3 grams of Cl2 contains 79.3/70.906 or 1.12 moles, to the justified number of significant digits…….
How do you find mole to mole ratio?
Find the ratio or the moles of each element by dividing the number of moles of each by the smallest number of moles. There are fewer moles of oxygen than any other element, so we will assume one mole of oxygen to establish the ratios. Use the mole ratio to write the empirical formula.
