Given :
Mass of urea = 5.6 g
To find :
The number of moles and molecules of urea
Formulae :
i. Number of moles = \(\frac{Mass\,of\,a\,substance}{Molar\,mass\,of\,a\,substance}\)
ii. Number of molecules = Number of moles × Avogadro’s constant
Mass...
Sharks retain more urea in their body fluid (blood) to make their blood isotonic to surrounding marine water (in order to maintain osmotic balance).
This helps them to prevent possible loss...
