How many moles of silver nitrate do 2.8881015 formula untied equal?
To find the number of moles in 2.8881015 formula units of silver nitrate, you first need to know the molar mass of silver nitrate (AgNO3), which is 169.87 g/mol. Then, you can use the formula: moles = formula units / Avogadro's number. Therefore, moles = 2.8881015 / 6.022 x 10^23 = 4.79 x 10^-24 moles.
How many formula units are present in 2.50 moles of CaCl2?
There are 3.01 x 10^24 formula units of CaCl2 in 2.50 moles. This can be calculated using Avogadro's number (6.022 x 10^23) and the formula units present in one mole of CaCl2 (3).
