Answer:
CHEBI:3312 - calcium dichloride
Explanation:
Calcium chloride is an inorganic compound, a salt with the chemical formula CaCl2.
The chemical symbol for sodium is Na
The answer is: the molecular formula of a compound is P₄O₁₀.
M(P₂O₅) = 2 · Ar(P) + 5 · Ar(O) · g/mol.
M(P₂O₅) = 2 · 31 + 5 · 16 · g/mol.
M(P₂O₅) = 142 g/mol; molar mass of empirical formula.
M(PₓOₙ) = 284 g/mol; molecular mass of unknown compound.
M(PₓOₙ) : M(P₂O₅) = 284 g/mol : 142 g/mol.
M(PₓOₙ) : M(P₂O₅) = 2 : 1.
