The molarity of HBr solution is 0.239 M
calculation
write the equation for reaction
that is LiOH +HBr → LiBr +H20
find the moles of LiOH used
moles =molarity x volume
=0.205 x 29.15 = 5.976 moles
by use of mole ratio between LiOH :HBr which is 1:1 the moles of HBr is therefore= 5.976 moles
Molarity of HCL= moles /volume
= 5.976/25 = 0.239 M
I believe you mean what amount of O2 contains 1.8 x 10^22 molecules.
Solution: Divide your number of molecules by the number of molecules in one mole (6.02 x l0^23)
02989 moles. Rounded to the nearest hundredths,.<span>0299</span>
D I believe peace out Hope this helps
