I have an aluminum cylinder; length =10cm and radius =.25cm
density of aluminum =2.70g/cm3
1Al atom =4.48*1023g
How many Al Atoms are in the cylinder?
Would you find the volume first? then do mass = d*v? and divide that by the mass of 1 Al atom?

Best ResponseYou've already chosen the best response.0i did Vcylinder = pi r^2(h) pi(.25^2)(10) = 1.96cm^3 then mass = d*v m= 2.70*1.96 = 5.292 then 5.292 / 4.48*10^23 = 1.18*10^23

Best ResponseYou've already chosen the best response.0in the question it says taht 1 atom of Al = 4.48 * 10^23 g

Best ResponseYou've already chosen the best response.0my solution is with the molar mass, your volume is incorrect i think. the volume is 1,96*10^3 cm^3

Best ResponseYou've already chosen the best response.0so my number of atoms is correct too? 1.18*10^23

Best ResponseYou've already chosen the best response.0uhm actually not :).. maybe just some different approximation..maybe the mass on your book is wromg
