How many grams of concentrated $HN{O_3}$ solution should be used to prepare $250ml\,\,of\,\,2.0M\,\,HN{O_3}$. The concentrated acid is $70\% HN{O_3}$

How many grams of concentrated $HN{O_3}$ solution should be used to prepare $250ml\,\,of\,\,2.0M\,\,HN{O_3}$. The concentrated acid is $70\% HN{O_3}$

A super saturated solution is a metastable state of solution in which solute concentration.

40% by weight solution will contain how much mass of the solute in 1L solution, density of the solution is 1.2 g/mL?

Iodine was added to a system of water and ${\rm{C}}{{\rm{S}}_2}$. The concentrations of iodine in water and ${\rm{C}}{{\rm{S}}_2}$ were found to be ${c_1}\;and\;{c_2}$ respectively. The ratio ${c_1}/{c_2}$ will not change only if :

A mixture of ethane and ethene occupies 41 L at 1 atm and $500\;K$. the mixture reacts completely with $\;\frac{{10}}{3}$ mole of ${O_2}$ to produce $C{O_2}\,and\;{H_2}{\rm{O}}$. The mole fraction of ethane and ethene in the mixture are $\left( {R = 0.082\;L\;{\rm{atm}}\;{{\rm{K}}^{ - 1}}\;{\rm{mo}}{{\rm{l}}^{ - 1}}} \right)$ respectively

$2.5{\rm{ }}\;L\;{\rm{ }}of\;{\rm{ }}NaCl$ solution contain 5 moles of the solute.What is the molarity ?
