is the answer 1.3?Can anyone solve this -->
A 6.90 M solution of KOH in water contains 30% by mass of KOH. Calculate the density of the
KOH solution?
[Molar mass of KOH = 56 g mol –1]
plzz

u tagged me? i dint get any alerts
Show me your solution.is the answer 1.3?
Hey I have one doubt.u tagged me? i dint get any alerts
yes it doesHey I have one doubt.
Does double bonds affect the bond angle?
Howyes it does
RoOkaYya GShow me your solution.
6.90 mol * 56 g/mol = 386.4Show me your solution.
NOO! not like this6.90 mol * 56 g/mol = 386.4
386.4 g ---> 30 % (0.3)
386.4 --->0.3
x = 1288 g
density of the solution ---> 1288 g / 1000 mL = 1.288 =1.3
i think lp lp coz itll affect those who r unpaired normallyHow
I mean bond angle decreases right?
if yes than which will affect more lp lp bonding or double bond on bond angle.
-_- i knw. thts how it is.NOO! not like this
6.90 M is molarity
now solve it.
which formula you used..-_- i knw. thts how it is.
I am getting 2.36.90 mol * 56 g/mol = 386.4
386.4 g ---> 30 % (0.3)
386.4 --->0.3
x = 1288 g
density of the solution ---> 1288 g / 1000 mL = 1.288 =1.3
Number 7i think lp lp coz itll affect those who r unpaired normally
molarity * molar mass = mass of the KOH in the solutionwhich formula you used..
and
I am getting 2.3
put in order of descending na.
YOU ARE WRONG!put in order of descending na.
so its 3>1>2
-_- abt wht u see literally i meant.YOU ARE WRONG!
Read the ques carefully.
i dont knowView attachment 48725 This is not right?
