Question

calculates the number of molecules in 90g of glucose​

Answer 1

Answer:

calculate the number of molecules of glucose present in its 90 gm ( molecules mass of glucose is 180u ) (6.02×1023 mol -1)

molar mass of glucose =180g/mol

no of moles is 90g

=90g/180g

=0.5 mol

Answer 2

Answer: 3.011×10 ^ 23 no. Of molecule of glucose.

Explanation: Molar mass of glucose = 180g/Mol

Number of Moles in 90 gm = 180/90 = 0.5 Mol

1 Mol contains = 6.023×10^23 no of molecule

0.5 Mol contains = 0.5 × 6.023×10^23

= 3.011× 10^23 no of

molecule
