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?

Did you find an error?
