lolkeinthatsghey Posted May 8, 2017 Report Share Posted May 8, 2017 What is the total number of atoms in 0.50 mol of 1,4-diaminobenzene, H2NC6H4NH2? A. 16.0 x 10^23B. 48.0 x 10^23 C. 96.0 x 10^23 D. 192.0 x 10^23 When I work out the problem I keep getting 3.0E23 0.50 mol * (6.0E23/1 mol) = 3.0E23 Am I doing something wrong? I feel comfortable doing stoichiometry, but now this problem makes me doubt myself. Reply Link to post Share on other sites More sharing options...
kw0573 Posted May 8, 2017 Report Share Posted May 8, 2017 So 3 × 1023 is the number of molecules, but we need to multiply by number of atoms per molecule, which is 16, to get 48 × 1023 atoms. You have the right idea I think it's just reading the question carefully. 2 Reply Link to post Share on other sites More sharing options...
