Think before you answer:
  
1. There is a class with \(32\) seats and \(31\) students. Another class has \(16\) seats and \(17\) students.

If there is a combined lecture for both classes, they will share the unfilled seat. How do we term this combination in chemistry?
 
2. Imagine you are counting a set of apples in a basket. You found that \(72\) apples are there. The average mass of an apple is \(200\) g. We have many options to represent the data. We can say six dozen or \(72\) apples or \(14400\) g or \(14.4\) kg of apples.

Similarly, the number of particles present in one mole of a substance is fixed as \(N = 6.022 \times 10^{23}\) . Then how many particles are there in \(2\) moles of an atom?
