Question

Calculate the mass of 5 × 1023 molecules of glucose

Answer 1

Answer:

the molar mass is 921,497.94

Explanation:

It is the molar mass of a glucose molecule (180.156) multiplied by 5 x 1,023

so 5 x 1,023 = 5115

than multiplied by 180.156 = 921,497.94

Answer 2

Answer:

0.830grams

Explanation:

one mole of glucose contains

$6.023 \times {10}^{23}$

molecules of glucose

fora mass of

$5 \times {10}^{23}$

mass of glucose is

$\frac{5 \times {10}^{23} }{6.023 \times {10}^{23} }$

$0.830grams$
