Question

how many grams of glucose will to be weight to get 0.2 mol c6h12o6​

Answer 1

Answer:

given mass of glucose=36g

Explanation:

no.of moles of glucose(n)=0.2mol

molecular mass of glucose=6(averageatomic

mass of C)+12

(average atomic

mass of H)+6

(average atomic

mass of O)

=6*12+12*1+6*16

=72+12+96

= 180u

molecular mass =molar mass

therefore,

molar mass of glucose=180 g/mol

n=given mass of glucose/molar mass

given mass of glucose=n×molar mass

=0.2×180

= 36g
