Calculate the total no of neutrons in 7mg of C^14

1.	Calculate the total no of neutrons in 7mg of C^14
Answer» Mass of 1 atom of C-14 = 14 a.m.u.Mass of 1 mole of C-14 = 14 grams<hr />(using unitary method)14 grams = 1 moleTherefore, 7 grams = 0.5 mole<hr />1 atom of C-14 has 8 neutrons0.5 mole of C-14 has\xa08 * NA\xa0=\xa08 * 6.022 * 1023\xa0=\xa04.8176 * 1024\xa0 neutrons
