Chemistry: An Introduction to General, Organic, and Biological Chemistry (12th Edition) - Standalone book, Chapter 7, Problem 7.71UTC , additional homework tip  2

a. Formula of a chemical species is given by AoB,

where A, B are the symbols of the elements, o and l are the number of A and B elements in the molecule.

Here, in first compound, o = 2, l = 2 and in second compound o = 6, l = 6. So, formulas are S2Cl2 and C6H6.

Formula used:

b. Molar mass of a compound,

AoB= o×Atomic Mass of A + l× Atomic  Mass of B        - (1)

c. The number of moles, n

n=(Mass of substancein grams)(MolarMass in g/mol) - (2)

Calculation:

b. Using equation (1), Molar mass of S2Cl2 = 2× 32.065 + 2×35.453 = 135.036 g/ mol

Molar mass of C6H6 = 6×12.011 + 1×6 = 78.066 g/ mol

Using equation (2),

Number of moles of S2Cl2 in 10 g = 10g135.036g/mol=0.074054mol

Number of moles of C6H6 in 10 g = 10g78.066g/mol=0.1281mol

Conclusion

Molecular formula of compound,1 = S2Cl2, molar mass=135.036 g/ mol and number of moles in 10 g of substance is 0.074054 mol.

Molecular formula of compound, 2 = C6H6, molar mass= 78.066 g/ mol and number of moles in 10 g of substance = 0.1281 mol.
