Answer 2

The number of molecules of sugar in 1 dm³ of 1M sugar solution is $6.022 \times {10}^{23}$

Given:

1 dm³ of 1M sugar solution.

To Find:

No. of molecules of sugar in 1 dm³ of 1M sugar solution.

Solution:

To find the No. of molecules of sugar in 1 dm³ of 1M sugar solution, we will follow the following steps:

As we know,

$1 {dm}^{3} = 1l$

Also,

$Molarity = \frac{no \: of \: moles}{volume \: in \: l}$

So,

$no \: of \: moles = molarity \times volume(l) = 1 \times 1 = 1$

Now,

1 mole of any substance contains Avogadro number of particles or molecules.

So,

1 mole of sugar will contain Avogadro number of molecules i.e

$6.022 \times {10}^{23}$

Henceforth, the number of molecules of sugar in 1 dm³ of 1M sugar solution is

$6.022 \times {10}^{23}$
