a) \(n_{CaCO3}=\dfrac{50}{100}=0,5\left(mol\right)\)
b) \(n_{CO2\left(dktc\right)}=\dfrac{11,2}{22,4}=0,5\left(mol\right)\)
Chúc bạn học tốt
a)
nCaCO3=\(\dfrac{m}{M}=\dfrac{50}{110}=\dfrac{5}{11}mol\)
nCO2=\(\dfrac{V}{22,4}=\dfrac{11,2}{22,4}=0,5mol\)
a. \(n_{CaCO_3}=\dfrac{50}{100}=0,5\left(mol\right)\)
b. \(n_{CO_2}=\dfrac{11,2}{22,4}=0,5\left(mol\right)\)
(Lưu ý: Ca = 40đvc)
a)ncaco3=\(\dfrac{m}{M}\)=\(\dfrac{50}{100}\)=0.5(mol)
b)nco2=\(\dfrac{V}{22.4}\)=\(\dfrac{11.2}{22.4}\)=0.5(mol)
