# How Much Time Would It Take to Distribute One Avogadro Number of Wheat Grains, If 1010 Grains Are Distributed Each Second? - CBSE (Science) Class 11 - Chemistry

ConceptLaws of Chemical Combination Avogadro Law

#### Question

How much time would it take to distribute one Avogadro number of wheat grains, if 1010 grains are distributed each second?

#### Solution 1

Avogadro number = 6.02 × 1023

Thus, time required

= (6.02 xx 10^(23))/10^10 s

= 6.02 xx 10^23 s

= (6.02 xx 10^23)/(60xx60xx24xx365) year

= 1.909 xx 10^6 year

Hence, the time taken would be 1.909 xx 10^(6) year

#### Solution 2

Time taken to distribute 10^10 grain =1 s

Time taken to distribute =  6.022 xx 10^23 "grain"

= (1 s xx 6.022 xx 10^23 "gain")/(10^10 "grain")

= (6.022 xx 10^13)/(60xx60xx24xx365)  = 1.9 xx 10^6 yr

Is there an error in this question or solution?
