Explanation:

Step 1: Define

10 mol F₂

Step 2: Identify Conversions

Avogadro's Number

Step 3: Convert

$10 \ mol \ F_2(\frac{6.022 \cdot 10^{23} \ molecues \ F_2}{1 \ mol \ F_2} )$ = 6.022 × 10²⁴ molecules F₂

Step 4: Check

We are given 1 sig fig. Follow sig fig rules and round.

6.022 × 10²⁴ molecules F₂ ≈ 6 × 10²⁴ molecules F₂

Answer 2

Answer:

Ans=   6.023 × 10²⁴ molecules F₂

Explanation:

moles can be converted to particles using Avogadro's constant (6.023 × 10²³) which is the number of molecules per mole of a substance. E.g In 1.5 moles of fluorine gas, there are (1.5) . (6.023 × 10²³) molecules of gas. its means in 10 moles of Fluorine gas there are (10).(6.023 x 10^23) molecules present .

Ans= 6.023 × 10²⁴ molecules F₂
