Answer:
4. 15
Explanation:
The given formula is:- 
1 mole of the salt contains 2 moles of nitrogen atom, 8 moles of hydrogen, 1 mole of sulfur and 4 moles of oxygen atom as can be seen from the formula.
Thus,
1 mole of salt contains total of 15 moles of the atoms which constitute the salt.
<u>Hence, 4. is the answer.</u>
Mass is the inside of an obeject such as what it’s made up of
It’s diagram because hydrogen has one proton and you’re not talking about ions so it needs another electron to stable itself
Whichever one has a negative enthalpy value.
Answer:
atoms Ti = 2.193 E23 atoms
Explanation:
- 1 mol ≡ 6.022 E23 atoms
- mm Ti = 47.867 g/mol
⇒ atoms Ti = (20.9 g Ti)×(mol/47.867 g)×(6.022 E23 atoms/mol)
⇒ atoms Ti = 2.193 E23 atoms
