Solid- molecules vibrate in place and tightly packed
liquid-molecules fur shape of container and can slide past each other
gas-molecules also fit shape of container and have the most room
Decomposition and synthesis is the answer
the moles would be 7.8125
divide 250g/32g/mol= 7.8125
Its a 1 to 1 mole ratio between O2 and HgO so they are the same number of moles.
Answer:
Molecular Formula = N₃P₃Cl₆
Explanation:
Molecular formula is calculated by using following formula,
Molecular Formula = n × Empirical Formula ---- (1)
Also, n is given as,
n = Molecular Weight / Empirical Formula Weight
Molecular Weight = 347.64 g.mol⁻¹
Empirical Formula Weight = 1 (N) + 1 (P) + 2 (Cl) = 115.88 g.mol⁻¹
So,
n = 347.64 g.mol⁻¹ ÷ 115.88 g.mol⁻¹
n = 3
Putting Empirical Formula and value of "n" in equation 1,
Molecular Formula = 3 × NPCl₂
Molecular Formula = N₃P₃Cl₆
