Question

how many number of moles are present in 90 gram of glucose​

Answer 1

Answer:

Glucose has a molar mass of 180.156 g/mol , which means that one mole of glucose molecules has a mass of 180.156 g . As you know, the number of molecules you get per mole is given by Avogadro's number. More specifically, one mole of any substance contains exactly 6.022⋅1023 molecules of that substance.

Answer 2

Answer:

No. of moles= Given mass/Molecular mass

So the no. of moles present in 90 gms of glucose is

= 90/180 as molecular mass of glucose C6H12O6

= 2

Hope this helps u!!
