i suppose 2 is mole?
OpenStudy (anonymous):
no it is molal means molality
OpenStudy (somy):
then what is the q? if molality is given what do u need to find?
OpenStudy (anonymous):
we have to find molarity

ohhhh
OpenStudy (anonymous):
this are concentration unit
OpenStudy (somy):
alright molarity= mole/volume
density= mass/volume volume= mass/density
molality= mole/mass mole= molality*mass
thus
we can make a formula
\[molarity= \frac{ molality \times mass }{ mass/density }\]
so \[\frac{ molality \times mass }{ 1} \div \frac{ mass }{ density}\]
so
\[\frac{ molality \times mass }{ 1} \times \frac{ density }{ mass}\]
so masses get cancelled
and we are left with
\[molarity= molality \times density \]
OpenStudy (somy):
bit of playing with formula and here u go a new formula lol
OpenStudy (somy):
do u get it? @Eli_Moses
