1.0 mole ---------- 6.02x10²³ molecules
4.5 moles -------- ?
4.5 * 6,02x10²³ / 1.0
= 2.709x10²⁴ molecules units
<u>Answer:</u>
3.67 moles
<u>Step-by-step explanation:</u>
We need to find out the number of
moles present in 350 grams of a compound.
Molar mass of
= 24.305
Molar mass of
= 35.453
So, one mole of
= 24.305 + (35.453 * 2) = 95.211g
1 Mole in 1 molecule of
= 
Therefore, number of moles in 350 grams of compound = 0.0105 * 350
= 3.67 moles
