5.85 g of NaCl is dissolved in 1 L of pure water . How do you calculate the number of ions in 1mL of this solution?
Answers
5.85 g of NaCl = 0.1 mol
1 L solution contain NaCl = 0.1 mol
1 ml solution contain NaCl = 0.0001 molone NaCl ionized Na+ and Cl- so that produce 2 ions
Total ion mole in 1 ml = 2x0.0001 mol
Number of iron in 1 ml=
#2# x#0.0001# x#6.023# x#10^23# Number of iron in 1 ml =
#1.2# x#10^20# ions
