Stoichiometry - Solved MCQs with Explanations

Below are important MCQs from Nursing Chemistry Chapter 1 (Stoichiometry). Each question includes the correct answer highlighted in green and a detailed explanation to help you understand the concept.

Q1 Easy Mole Concept

One mole contains how many particles?

A 6.022 x 10^22
B 6.022 x 10^23
C 6.022 x 10^24
D 3.011 x 10^23
Explanation

Avogadro's number (6.022 x 10^23) = particles in one mole. This fundamental constant connects atomic and macroscopic scales.

Q2 Easy Empirical & Molecular Formulas

Empirical formula of glucose (C6H12O6) is:

A C6H12O6
B CH2O
C C2H4O2
D C3H6O3
Explanation

Dividing all subscripts by 6 gives CH2O as the simplest whole number ratio of atoms in glucose.

Q3 Medium Limiting Reagent

The limiting reagent is:

A Present in excess
B Completely consumed first
C Most expensive
D The catalyst
Explanation

The limiting reagent is consumed first, determining the maximum amount of product formed. Other reagents are in excess.

Q4 Easy Percentage Composition

Percentage of oxygen in H2O:

A 11.1%
B 88.9%
C 50%
D 66.7%
Explanation

Molar mass H2O = 18. Mass of O = 16. (16/18) x 100 = 88.9%. Hydrogen = 11.1%.

Q5 Easy Mole Concept

Balanced equations conserve:

A Only mass
B Only charge
C Both mass and charge
D Neither
Explanation

Balanced equations conserve both mass (same atoms each side) and charge (equal total charge), following Conservation of Mass.

Q6 Medium Empirical & Molecular Formulas

Molecular formula from CH2O with molar mass 180:

A CH2O
B C2H4O2
C C6H12O6
D C3H6O3
Explanation

Empirical mass = 30. Factor = 180/30 = 6. Molecular formula = C6H12O6 (glucose).

Q7 Easy Avogadro's Number

Avogadro's number is defined as:

A Atoms in 1g H
B Particles in 1 mole
C Molecules in 1L gas
D Ions in 1 mole
Explanation

NA = 6.022 x 10^23 = number of particles in one mole of any substance.

Q8 Medium Mole Concept

2 moles CH4 burning produces how many moles CO2?

A 1
B 2
C 3
D 4
Explanation

CH4 + 2O2 -> CO2 + 2H2O. 1:1 ratio means 2 mol CH4 produces 2 mol CO2.

Q9 Hard Avogadro's Number

Which has the most atoms per mole?

A O2
B H2O
C CO2
D CH4
Explanation

CH4 = 5 atoms/molecule (1C + 4H), CO2 = 3, H2O = 3, O2 = 2. So 1 mol CH4 has most atoms.

Q10 Easy Mole Concept

Molar mass of NaCl:

A 35.5 g/mol
B 58.5 g/mol
C 23 g/mol
D 40 g/mol
Explanation

NaCl = Na(23) + Cl(35.5) = 58.5 g/mol.
