Question

how many moles of glucose are contained in 8.3 x 10^21 molecules of glucose

Answer 1

approximitly 0.013787375 moles 

Answer 2

Answer:

So, no. of moles of glucose = 0.0138

Explanation:

No. of molecules of glucose = $8.3 \times 10^{21}$

Moles is related with number of molecules as:

$mol=\frac{No.\ of\ molecules}{Avogadro's\ no.}$

Avogadro's no. = $6.02 \times 10^{23}$

moles of formaldehyde

                $=\frac{8.3\times 10^{21}}{6.02\times 10^{23}} \\=0.0138\ mol$

So, no. of moles of glucose = 0.0138
