find mass of oxygen by subtracting mass of phosphorus from the total mass
divide the masses by the molar mass to get moles
divide moles by the smallest amount of moles
multiply by 2 to get a nice number
P4O5
Answer:
That's not true. It would in fact be physical.
Explanation:
physical change: some of its physical properties may change but its identity does not
A pseudoscientific theory
6.6 g
Explanation:
The mole ration between CaCO₃and CO₂ is 1 : 1
Because the molar mass of CaCO₃ is 100.0869 g/mol the amount of moles used in this chemical reaction is;
15/ 100
This will be similar to the moles of CO₂
Because the molar mass of CO₂ is 44g, then well multiply by the moles;
15/100 * 44
= 6.6 g
