Question

Calculate the number of Potassium ions in 7.45g of KCl?​

Answer 1

$answer$

of moles of K2O=Mass in gram/Molar mass=7.45g/94g/mol=0.079mol. since each molecule of K2O contains two potassium ions(K+),total number of potassium ion is given by 4.76x10²²x2=9.52x10²²ions.

Hope it's helps you..
