How many atoms are in 1.7 mols of CHF3

Chemistry
1 answer:
erastovalidia [21]2 years ago
5 0

Given :

Number of moles of CHF₃ is 1.7 .

Solution :

We know, 1 mole of any complex contains 6.022 × 10²³ molecules.

Let, 1.7 moles of CHF₃ contains n numbers of molecules.

So, n = 1.7 × 6.022 × 10²³ molecules

n = 10.2374 × 10²³ molecules

n = 1.0237 × 10²³ molecules

Hence, this is the required solution.

DerKrebs [107]

Answer:

3.65 g / ml correct to 3 sig. fig.

Explanation:

The computation of the concentration required is shown below:

As we know that

[A] = mass of solute ÷ volume of solution

Before that first find the mass of solute

Given that

Initial weight = 5.55g

And,

Final weight = 92.7 g

So,

Mass of KCl is

= 92.7 - 5.55

= 87.15 g ~ 87.2 g

Now the KCi is fully dissolved, so the volume is 23.9 ml

So,  concentration is

= 87.2 g ÷ 23.9 ml

= 3.65 g / ml correct to 3 sig. fig.
