How many atoms and moles are in 79g of potassium?

1.	How many atoms and moles are in 79g of potassium?
Answer» No. of grams of Potassium in 1 mole = 39 g Mass GIVEN = 79 g No. of MOLES = 79/39 = 2.025 No. of atoms in 1 mole of Potassium = 6.02210²³ No. of atoms in 2.025 moles of Potassium = (6.0222.025) * 10²³ = 12.194*10²³ I HOPE this HELPS.

Answer»

No. of grams of Potassium in 1 mole = 39 g

Mass GIVEN = 79 g

No. of MOLES = 79/39

= 2.025

No. of atoms in 1 mole of Potassium = 6.022*10²³

No. of atoms in 2.025 moles of Potassium = (6.022*2.025) * 10²³

= 12.194*10²³
