Best ResponseYou've already chosen the best response.0I dont think we need molar mass since the grams would cancel out and we need to know the mass of a single Zinc atoms.

Best ResponseYou've already chosen the best response.0@Jhannybean Your answer is in Zn atoms. Isnt it supposed to be the gram of one atom?

Best ResponseYou've already chosen the best response.0Maybe it is 130.8g Zn/65.38g Zn=2.00 mol Zn \[\frac{ 2.00 mol Zn }{ 1 }\times \frac{ 6.022\times10^{23} Zn atoms }{ 1mol Zn }=1.2044\times10^{24}Zn atoms\]=1.2044 x 10^24 Zn atoms Divide 130.8 grams by that big number.

Best ResponseYou've already chosen the best response.0Not sure why the question tells us 130.8 g of Zn contains 6.022 x 10^23 atoms. (Is it trying to trick us or is it an exception?)
