Answer:

Molecular formula =  H₂S₂O₈

Explanation:

Given data:

Empirical formula = HSO₄

Formula mass = 194.13 amu

Molecular mass = ?

Solution:

Molecular formula = n × empirical formula

n = molar mass of the compound / empirical formula mass

Empirical formula mass = 1.008 + 32.065 + 16× 4

Empirical formula mass = 97.073

n = 194.13 / 97.073

n= 2

Molecular formula = n × empirical formula

Molecular formula = 2  (HSO₄)

Molecular formula =  H₂S₂O₈

telo118 [61]

Answer:

2.89 g/cm^3

Explanation:

Since density equals mass over volume (or also seen as d=\frac{m}{v} ), simply divide 66.5 grams by 23.0 cm. This will output an answer of 2.89 g/cm^3.

Which of the following two combinations of reactants is more appropriate for the preparation of p-nitrophenyl phenyl ether? Fluo
VladimirAG [237]

Answer:

p-fluoronitrobenzene and sodium phenoxide is more appropriate

Explanation:

An ipso substitution is required to form p-nitrophenyl phenyl ether.

For this ipso substitution, an alkoxide anion needs to attack as a nucleophile at the carbon atom attached to fluorine atom and thereby substitute that F atom.

p-nitrophenoxide is an weak nucleophile as compared to phenoxide due to presence of electron withdrawing resonating effect of nitro group at para position.

p-fluoronitrobenzene is a good choice for nucleophilic attack by alkoxide anion as compared to fluorobenzene due to higher positive charge density at carbon atom directly attached to F atom. Higher positive charge density arises due to presence of electron withdrawing resonating effect og nitro group at para position.

So, p-fluoronitrobenzene and sodium phenoxide is more appropriate
