a tank in an apartment is filled with x L of water. If 50 L of water is being used every hour,
will be left over after 3 hours.
Answers
Step-by-step explanation:
Since its a mathematical question with chemistry involved. Let’s us proceed in a non bias scientific way.
Let the amount of water in the bucket be x.
Let’s assume the Value of x be 1 ltr.
Therefor, X=1
According to the question every hour 50% of the water is taken out.
Thus,
After 1st hour , amount of water in bucket left = x-50% of x= 1–50/100*100=0.50
After 2nd hour, 0.50 - 50% of 0. 50= 0.50–50/100*0.50=0.25
After 3rd hour, 0.25 - 50% of 0.25= 0.25–50/100*0.25= 0.125
…. and so on till the amount becomes insignificantly small. However, there is a catch, Water essential is a a combination of Hydrogen and Oxygen atoms and each molecule of water contains two hydrogen and one oxygen atom and hence the scientific formula of water is H20.
Now, armed with the information mentioned above, we can convert 1 ltr of water into its molecular content.
The water has a molecular weight of 18. The liter of water has 1000 grams. The number of moles is 1000/18 = 55.556 moles. The number of molecules is therefore 6.022*10^23* 55.556 = 3.346*10^25 molecules.
FYI, 1 mole molecule of any substance has avogadro number of molecules(6.022*10^23)
Hurray, Now this are easier we just need to take 50% of molecules out after every hour till there are no molecules left and we will get number of hours required to empty the bucket.
Though, for your question it is impossible to derive the answer as the pivotal information, which is amount of water in the bucket is not given.
Hope it helps. May the world be at peace :
