a bottle of concerntrated HCL (36.5) was labelled as 37% (w/w) and density 1.19m/l.What is hcl mol..

Answer / umesh patel

the molarity of the resultant solution will be around 12
molar
molarity=1.19*1000*37/100*36.5=12 m

a bottle of concerntrated HCL (36.5) was labelled as 37% (w/w) and density 1.19m/l.What is hcl mol..

Answer / mandal

d= m/v

calculate mass for 1L of Hcl

1.19*1000= 1190g . 1190 g of entire solution 37% is Hcl- hence

37/100*1190= 440.3 g is Hcl

M= mole/L = W/mw*1L= 440.3/36.5*1L= 12.06 M

Answer / dave

37% (w/w) implies 37g of HCl in 100 g of solution.
37g is 37/36.5 = 1.01 moles HCl.

However, this is dissolved in 100 g of solution not 100 mL of solution. The actual volume present can be determined from the density of 1.19 g/mL.
100 g/V mL = 1.19, therefore the actual solution volume is 100/1.19 = 84 mL.

The concentration is 1.01/84 mol/ml = 0.012 mol/ml
Or, in mol/L this is 1000 x 0.012 = 12 mol/L.


If this had been 37% (w/v) this would have been 37 g HCl in 100 mL solution and no correction for density would have been needed. The concentration in that case would have been 10.1 mol/L

a bottle of concerntrated HCL (36.5) was labelled as 37% (w/w) and density 1.19m/l.What is hcl mol..

Answer / sagar pawar

molarity{M}=V*B*P*D/100*m
Where V=Volume,B=Basicity, P=Purity, D=density
m= Molecular wt.
M=1000*1*37*1.19/100*36.5
= 12.06 M

a bottle of concerntrated HCL (36.5) was labelled as 37% (w/w) and density 1.19m/l.What is hcl mol..

Answer / gursharn singh kang

molarity =( given percentage *density/molecular wt.)*10

so M WT. of hcl=36.46

i.e. molarity=(37*1.19/36.46)/10

=12.0762 M

a bottle of concerntrated HCL (36.5) was labelled as 37% (w/w) and density 1.19m/l.What is hcl mol..

Answer / bujji kanchi

37% means 37 g of solute dissolved in 100 ml solvent.

37g/1000 ml=1N
37g/100 ml= 10 N

Answer / shashi

Strength = %assay*density*100/mol wt* 1000
=37*1.19*100/36.5*1000
=0.12 M
