1 liter of water at 4 degree C has 1000 gms of mass. (this varies depending on whether water is pure, sea water, at what temperature, atmospheric pressure)
Molecular weight 18gm/mol.
Concentration = 1000/18 = 55.5 mol/ltr.
PS : kayi saal me try mari se mole concept ki. Manne jo sabte asan lagya uste kaadh di. galat ho to dalle mat mariyo eeb!

Agar MDH masala hai to Mahasiyan di hatti kuch log Methi dhaniya haldi bhi sochte hain. In case of aviation it is Minimum Decent Hieght

Step down transformer
Kyonki jo bijli bijlighar se aati hai uski voltage bahut hogh hoti hai aur wo ghar ke lattu pankha freeze washing machine motor ityadi ko foonk sakti hai aur aapko fir se kuch din adivasi jeevan vyatatit na karna pade isliye bijli vibhag wale aapke ghar ke pados mein transformer rakhte hain.
Kuch haramkhor uska tel bhi churate hain kisi ko aisa na karne dein.
bijalighar se hi seede low voltage kyo naa bhej di jaati????
last baat sahi kahi..kuchh oot naa maante aisa kiye bina...
bhaang,daaru ka kharche ki liye kuchh bhi kar lete hai...

Kyonki transmission mein enegy losses bahut jyada honge agar low votage bheji to.
yahan bhi kuch haramkhor honge jo rah mein kundi ger denge free ki bijli khatar

Another reason for step downing is to make it safer for use in homes i.e., less lethal. In many foreign countries, the usable voltage is 110V instead of 220V.

Urmila Ji... I have a different thought to be shared...This is true that step down make current less lethal. There is no difference in terms of lethalness even if you are using 110 or 220V.....it is not the voltage alone which decide the lethalness....Frequency and power has to be taken into account....in foreign countries voltage is 110V but at the same time frequency goes to 60Hz...In India...frequency is 50Hz which means it allow one to save his/her life every 1/50th of a second.... while the chances in foreign county are seems to be better which allow one to save his/her life every 1/60th second...but at the same time, time duration to save life is far better in india...as per every single pulse( because human mascular response to save his/her life is not quick enough as in comparison to the frequency) in both the case power is going to be almost same...b/c P=(I) square*V .....Hope this helps.....QUOTE=urmiladuhan;272112]Another reason for step downing is to make it safer for use in homes i.e., less lethal.

pls do tell us...why specifically you have taken water at 4 degree only?

Pure water reaches its maximum density at approx. 4 degree C.
