Chemistry HW: Molarity?
How can I calculate the molarity of copper (II) chloride if I am given only that there is a 100 mL of copper (II) chloride?
* a conversion factor of 22.4 L can't be used b/c the solution is not at STP*
Is there no other way than to know the # of grams of the substance?

2KOH + H2SO4 -> K2SO4 + 2H2O (first write out a stability equation) M=mol/L (use this formulation because of the fact it quite is a titration situation) *mol H2SO4 = ? *Molarity or (M) H2SO4 = 0.one thousand *mL= 24.sixty 8 yet convert to L = 0.0246 only plug each and all the cost on your equation 0.one thousand=molH2SO4/.0246 molH2SO4=0.00246 now convert your mol of KOH to mole of H2SO4 by way of utilising the equation which you have above 0.00246H2SO4 (2)KOH/(a million)H2SO4 = 0.00492mol KOH then repeat the comparable technique as you probably did for the 1st one *mol KOH=0.00492 *Molarity=??? *mL=25.4 convert to L=0.0254 M=0.00492/0.0254 M=0.19377 ( be sure you write it 2 decimal bypass) 19.37 x 10^-2 M KOH desire this help!! :)
