Mohon bantuannya kak…​

Penjelasan:

Mr CaCO3 = 100

Mr CaO = 56

massa CaCO3 = 1 kg = 1000 gram

mol CaCO3 = massa / Mr

=> 1000 / 100

=> 10 mol

Perbandingan koefisien ~ perbandingan mol

CaCO3 : CaO : CO2 = 1 : 1 : 1 mol CaO = 10 mol

massa CaO = n x Mr

=> 10 x 56

=> 560 gram

mol CO2 = 10 mol

V STP = n x 22,4

=> 10 x 22,4

=> 224 L
