How many moles are in 22 6 grams of AgNO3?

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 many moles are in 25.5 grams of silver?
