a)
Na=6,02*10^23 at/mol
w 1 molu H2O ------2mol H
w 0,6 mola H2O ----x
x=(0,6*2)/1=1,2mola at H
w 1 molu H2O ------1mol O
w 0,6 mola H2O -----y
y=(0,6*1)/1=0,6mola at O
b)
M(H)=1g/mol
M(O)=16g/mol
w 1molu H2O -----2*1g/mol H
w 0,6mola H2O ----x
x=(0,6*2*1)/1=1,2g
w 1molu H2O -----16g/mol O
w 0,6mola H2O ----y
y=(0,6*16)/1=9,6g
