About Fundamental Concepts of Chemistry
Mole calculations connect mass, number of particles and Avogadro's number, while balanced equations provide the mole ratios used in stoichiometry. Questions cover limiting and excess reactants, theoretical yield and percentage yield, including identifying which reactant is consumed first and comparing the actual product with the maximum possible product.

The weight of 350 ml of a diatomic gas at 0°C and 2 atm pressure is 1 g. The weight of one atom is (N is the Avogadro's number):
12 g of carbon combines with 64 g of sulphur to produce CS2. 12 g of carbon also combines with 32 g of oxygen to form CO2. 10 g of sulphur combines with 10 g of oxygen to produce SO2 . This data illustrates the:
Caffeine has a molecular mass of 194 g. If it contains 28.9% by mass of nitrogen, number of atoms of nitrogen in one molecule of caffeine is:
When 3.0 litre solution of normality N is mixed with 5.0 litre of 4M HCl, then the resultant solution has normality 10. Find the value of N.
A 0.1097 gm sample of As2O3 requires 26.10 ml of KMnO4 solution for its titration. The molarity of KMnO4 solution is:
When pentane C5H12 is burned in excess of oxygen, the products of the reaction are CO2(g) and H2O (l). In the balanced equation for this combustion, C5H12(g) + O2 (g) → 5CO2(g) + 6H2O (l) the coefficient of oxygen should be:
