Mole Calculations Help Please

[From: ] [author: ] [Date: 11-09-16] [Hit: ]
Since there are 4 Cl atoms for each molecule,4(3.948 x 10^-4 mol) = 1.Or 1.......
How many moles of chlorine atoms are present in a 9.2 x 10 ^ -2 g sample of zirconium(IV) chloride, ZrCl subscript 4?

Please step by step explanations and answers please please thank you so much <3

-
1 mole of ZrCl4 = 233.04 g

9.2 x 10^-2 g ZrCl4 x 1 mol / 233.04 g = 3.948 x 10^-4 mol of ZrCl4

Since there are 4 Cl atoms for each molecule,

4(3.948 x 10^-4 mol) = 1.579 x 10^-3 mol Cl

Or 1.6 x 10^-3 mol Cl
