Instructions: Use the information provided and the calculator (click "Open Calculator" for each question) to solve the following problems. Show your working where possible and include units in your answers.
Key Information: Avogadro's constant = \( 6.02 \times 10^{23} \), Molar gas volume at r.t.p. = \( 24 \, \text{dm}^3 \)
amount of substance (mol) = mass (g) / molar mass (g/mol)
Avogadro's constant (Nₐ) = \( 6.02 \times 10^{23} \)
Molar gas volume at r.t.p. = \( 24 \, \text{dm}^3 \)
1 dm³ = 1000 cm³
Atomic masses (g/mol):
