Question

Calculate the number of atoms in a 7.52 x 10 g sample of carbon. atoms atoms

Answer 1

thank a lot . good luck

atomic mass of brbon = 12 g/mol DATE TOIT for this question we need mole concept 1 mole - 6.022x10 23 Particle Porticle may be 1. atoms 2 ions - 3 - molecules Step 1 to Calculate the mole Number of Carbon Given mass of Carbon in Lamble mole Number of Corbem = = - Atomic mass of Carbon - 7.52X 10 g mole of Corben = = 626.66 mole 12 g/mol Step-2 to calculate the Number of Carbon atom in 626.66 mole Carbon We know 1 mol = 6.022 X 10 23 Carbon atom Now total Number of Carbon atom in 626.66 mole Carbon = 626.66 X 6:02ZX1023 3773.74 x 1023 v OR . 77374 x 1026 catem after round off it will be 3.774 X 10 26 atom Thank you very much. hope this will help you PAGE
