If 2500 grams of H2SO4 react with excess NH3 according to the illustration, the amount of ammonium sulfate that can be produced would be 3,370.92 grams. If only 3100 grams of ammonium sulfate were produced, the percentage yield would be 91.96%.

<h3>Stoichiometric calculations</h3>

From the equation of the reaction:

2NH3(aq) + H2SO4(aq) → (NH4)2SO4(aq)

The mole ratio of H2SO4 and (NH4)2SO4 is 1:1

Mole of 2500 grams H2SO4 = 2500/98 = 25.51 moles

Equivalent mole of (NH4)2SO4 = 25.51 moles

Mass of 25.51 moles (NH4)2SO4 = 25.51 x 132.14 = 3,370.92 grams

If 3100 g of (NH4)2SO4 were actually produced, the percentage yield would be:

Percent yield = 3100/3370.92 x 100 = 91.96%

A gaseous fuel mixture stored at 747 mmHg and 298 K contains only methane (CH4) and propane (C3H8). When 11.1 L of this fuel mix
Alisiya [41]

Answer:

M_f=38.8\%

Explanation:

From the question we are told that:

Pressure P=747mmHg

Temperature T=298K

Volume V=11.1

Heat Produced Q=780kJ

Generally the equation for ideal gas is mathematically given by

 PV=nRT

 n= (747/760) *11.1/ (0.0821*298)

 n=0.446mol

Therefore

 x+y=0.446

 x=0.446-y .....1

Since

Heat of combustion of Methane=889 kJ/mol

Heat of combustion of Propane=2220 kJ/mol

Therefore

 x(889) + y(2220) = 760 ...... 2

Comparing Equation 1 and 2 and solving simultaneously

 x=0.446-y .....1

 x(889) + y(2220) = 760 ...... 2

 x=0.173

 y=0.273

Therefore

Mole fraction 0f Methane is mathematically given as

 M_f=\frac{x}{n}*100\%

 M_f=\frac{1.173}{0.446}*100\%

 M_f=38.8\%

A chemical formula for a molecular compound represents the composition of
Leni [432]

Answer:

A chemical formula for a molecular compound represents the composition of <u><em>a molecule.</em></u>

Explanation:

Chemical formulas are alphanumeric expressions that are used to indicate the composition of chemical substances. They consist of chemical symbols that indicate the elements that form a compound; The number of atoms provided by each element is also indicated by the use of a subscript, that is, a small number that is placed below and to the right of each element that so requires.  When an element does not have a subscript, it is understood that there is only one atom of it in the substance.

Each molecule corresponds to a chemical formula, as well as a name according to the rules of the chemical nomenclature.

Then, <u><em>a chemical formula for a molecular compound represents the composition of a molecule.</em></u>
