Question

Calculate the mass percentage of NA and Cl atoms in common salt.( given molar mass NaCl = 58.5g / mol )​

Answer 1

Answer:

Heya!

Weight of 1 molecule NaCI = 58.5

Weight of Na ion = 23

Weight of Cl ion = 35.5

$Mass \: \% = \frac{weight \: of \: ion}{weight \: of \: molecule \: NaCI} \times 100$

22.99(cut) 23

______

58.5 × 100

$na\% \: mass \: is \: 39.3\%$

$Cl \: \% \: mass \: is \: 60.7\%$
