Question

I'm back in college at the age of 50 and found out there's newelements on the periodic chart. Please let me know if you can verify I calculated thefollowing correctly. Ques: calculae the number of molecules in each of thefollowing samples: A. 0.25 mole of sucrose(C12H22O11) The formual mass = 342 I multiplied that by 0.25 the answer I got was 85.50 x 6.022 x1023   or   5.15 x 1025 Is that correct?

Is that correct?

Explanation / Answer

We Know that :         According toAvogardo's law :           1 moleof any substance contains 6.023 x 1023 particles       Given :                    0.25 mole of Sucrose                     1 mole of Sucrose = 6.023 x 1023 molecules                     0.25 mole of Sucrose = 0.25 x  6.023 x1023 molecules                                                          = 1.50 x 1023 molecules
