How many moles is 2.80 x10 24 atoms of silicon?

Let x moles of silicon contains 2.8x10^24 atoms. 6.02x10^23 atoms are present in 1 mole of Si. Therefore 2.80x10^24 atoms are present in = 2.8x10^24/6.02x10^23 = 4.65 moles of Si. 3.0. read more

2.80 x 10 ^ 24 / 6.022 x 10 ^ 23 atoms = 4.65 mol. your answer should be to 3 significant digits because that's the least number you had in your original questions. 2.80 is 3 SD, so your answer should also contain 3. You cannot be more exact than the number that is least exact. read more
