A) One molecule of glucose contains two times more atoms of hydrogen than atoms of carbon, then
B) One molecule of glucose contains 6 carbon atoms, then number of glucose molecules is 6 times less than number of carbon atoms:
"N(C_6H_{12}O_6)= \\frac{N(C)}{6} = \\frac{1.290\\times10^{21}}{6} =2.150\\times10^{20}"
C)
"n=\\frac{N}{N_A}""n(C_6H_{12}O_6)=\\frac{N(C_6H_{12}O_6)}{N_A}=\\frac{2.150\\times10^{20}}{6.022\\times10^{23}}=3.570\\times10^{-4} mol"
d)
"m=M\\times n""M(C_6H_{12}O_6) = 180.16\\frac{g}{mol}"
"m(C_6H_{12}O_6) = 180.16\\times 3.570\\times10^{-4} =6.432\\times10^{-2}g"
