A sample of phosphorus has 0.25 moles of P4 molecules
8 How many p. molecules are there? OD Flow many P atoms are there?
• (iii) How many moles of P atoms ate there in the sample?
(iv) What is the mass of the sample?​

Answer 1

Answer:

mole of P4 molecule consists of 6.023*10^23 molecules. Therefore, 0.25 mole of P4 consists of 6.023*10^23 *0.25 molecules of P4. Therefore, 0.25 mole of P4 = 1.50575 * 10^23 molecules of P4.
