Sagot :
Moles of Carbon dioxide(CO₂) : 0.693
Further explanation
A mole is a unit of many particles (atoms, molecules, ions) where 1 mole is the number of particles contained in a substance that is the same amount as many atoms in 12 gr C-12
1 mole = 6.02.10²³ particles
While the number of moles can also be obtained by dividing the mass (in grams) by the molar mass of the element or molecule
So looking for moles we can search in 2 ways
- 1 . Avogadro's number
n = N : No
N = number of gas particles
No = Avogadro number (6.02.10²³)
n = number of moles
- 2. Molar mass
n = m : M
m = mass
M = relative molecular mass
Given
mass CO₂ = 30.5 grams
Required
moles CO₂
Solution
Molar mass of CO₂ : 44 g/mol
Input the value :
mol = mass : molar mass
[tex]\tt mol=\dfrac{30.5~g}{44~g/mol}\\\\mol=\boxed{\bold{0.693}}[/tex]
