$2KClO_3 \xrightarrow{t^o} 2KCl +3 O_2$
a) n O2 = 48/32 = 1,5(mol)
n KClO3 = 2/3 n O2 = 1(mol)
m KClO3 = 1.122,5 = 122,5(gam)
b) n O2 = 44,8/22,4 = 2(mol)
n KClO3 = 2/3 n O2 = 4/3 (mol)
m KClO3 = 122,5.4/3 = 163,33(gam)
\(a.\)
\(n_{O_2}=\dfrac{48}{32}=1.5\left(mol\right)\)
\(2KClO_3\underrightarrow{^{t^0}}2KCl+3O_2\)
\(1...............................1.5\)
\(m_{KClO_3}=1\cdot122.5=122.5\left(g\right)\)
\(b.\)
\(n_{O_2}=\dfrac{44.8}{22.4}=2\left(mol\right)\)
\(2KClO_3\underrightarrow{^{t^0}}2KCl+3O_2\)
\(\dfrac{4}{3}.................2\)
\(m_{KClO_3}=\dfrac{4}{3}\cdot122.5=163.3\left(g\right)\)
