Respuesta :
The total number of moles in 20 grams of Calcium carbonate compound is 0.2 mole.
The number of moles can be calculated by the formula ,
[tex]\bold {n = \dfrac wm}[/tex]
Where,
n- number of moles
w- given mass of the compound = 20 g
m - molar mass of compound = 100 g/mol
put the values in the formula
[tex]\bold {n = \dfrac {20\ g}{100\ gm/mol} }\\\\\bold {n =0.2}[/tex]
Therefore, the total number of moles in 20 grams of Calcium carbonate compound is 0.2 mole.
