Step 1:
For part i), we need to find the number of atoms in 4 moles of nitrogen. Since 1 mole of nitrogen contains 6.022 x 10^23 atoms (Avogadro's number), 4 moles would contain: \text{Number of atoms} = 4 \ \text{moles} \times 6.022 \times 10^{23} \ \text{atoms/mole} = 2.4088 \times 10^{24} \ \text{atoms}

Final Answer
i) 2.4088 x 10^24 atoms ii) 4.8176 x 10^23 atoms
