Answer : The number of glucose molecule are, [tex]42.55\times 10^{23}[/tex]
Explanation : Given,
Mass of [tex]C_6H_{12}O_6[/tex] = 1273 g
Molar mass of [tex]C_6H_{12}O_6[/tex] = 180.156 g/mole
First we have to calculate the moles of [tex]C_6H_{12}O_6[/tex].
[tex]\text{Moles of }C_6H_{12}O_6=\frac{\text{Mass of }C_6H_{12}O_6}{\text{Molar mass of }C_6H_{12}O_6}=\frac{1273g}{180.156g/mole}=7.066moles[/tex]
Now we have to calculate the number of molecules of glucose.
As, 1 mole of glucose contains [tex]6.022\times 10^{23}[/tex] number of glucose molecules
So, 7.066 mole of glucose contains [tex]7.066\times 6.022\times 10^{23}=42.55\times 10^{23}[/tex] number of glucose molecules
Hence, the number of glucose molecule are, [tex]42.55\times 10^{23}[/tex]
