OpenStudy (jfraser):

OpenStudy (anonymous):

Im not good at math and when the math didnt match up with any of the answers i just guessed A since it was closest

OpenStudy (jfraser):

OpenStudy (anonymous):

use must be confused on the atoms because its neither moles molar mass nor mass

OpenStudy (anonymous):

wellwhen dealing with questions like these when your given lets say 6.33 X10^26 atoms or molecules you divide by avogadros number to get the number of moles|dw:1424027752871:dw|
