Answer:
4 atoms
Explanation:
1 ml has 1/22400 moles at STP.1 mole = 6.022 x 1023molecules. So number of molecules of ammonia in 1 ml = 6.022 x 1023/22400. Now, multiply this number by 4 to get the total number of atoms as each molecule of ammonia has 4atoms
Explanation:
✔1 ml has 1/22400 moles at STP.
1 mole = 6.022 x 10^23 molecules.
=》So no. of molecules of NH3 in 1 ml
= 6.022 x 1023/22400.
= 0.027 x 1021
=》Now, multiply this no. by 4 to get the total no. of atoms as each molecule of ammonia has 4 atoms ( 1 N and 3 H).
= 4 x 0.027 x 1021
= 0.1075 x 10 21
= 1.075 x 10 20
✔Therefore, 1ml oh NH3 contains 1.075 x 10^20atoms at STP.
