Answer:
8 mol
Explanation:
Step 1: Calculate the mass of PtCl₄ in the sample
10.00 grams of a sample of hydrated PtCl₄ are heated and lose 3.00 g of water. The mass of PtCl₄ is:
mPtCl₄ = 10.00 g - 3.00 g = 7.00 g
Step 2: Calculate the moles corresponding to 7.00 g of PtCl₄ and 3.00 g of H₂O
The molar mass of PtCl₄ is 336.9 g/mol.
7.00 g × 1 mol/336.9 g = 0.0208 mol
The molar mass of H₂O is 18.02 g/mol.
3.00 g × 1 mol/18.02 g = 0.166 mol
The molar ratio of H₂O to PtCl₄ is:
0.166 mol H₂O/0.0208 mol PtCl₄ ≈ 8 mol H₂O/ 1 mol PtCl₄
Reactants are what make up the product.
D. ) After heating, it would be all of the above....
First one is reactants and then second one is products
In regards to the given question, option “1” is the correct
option. When propane is burnt to complete combustion, it results in the
formation of two completely different substances. It actually forms a mixture
of water vapour and carbon dioxide. When NaCl or sodium chloride is melted, it
does not result in the formation of any new substance and so option “2” cannot
be the correct answer. With regards to deposition of carbon dioxide and solidification
of water, no new substance gets formed and so can be neglected as the answer to
the question.
