The experiment is repeated with 1.0 M ethanoic acid to replace the sulphuric acid. Calculate the volume of ethanoic acid, CH3COOH needed to neutralize 25mL of potassium hydroxide solution
Molar mass of ethanoic acid = 60.052 g/MolMolar mass of KOH =56.105625/56.1056= 0.446mol0.446×60.052= 26.76ml of CH3COOH

Zinc and HCl react to form ZnCl2 and hydrogen gas. How many grams of H2 can be produced if 4.25g of Zinc react with 25 mL of 3.00M HCl?
25 mL x (1L/1000 mL) x (4 mol HCl/1L) x (1 mol Zn/2 mol HCl) x (65.38 g Zn/1 mol Zn) = 3.269g = ~ 3.3g of ZnParts explained25 mL...

How will blue and red litmus paper react with neutralisation reactions and why? These are the reactions: HCl+NH3, CH3COOH+NH3, HCl+NaOH, CH3COOH+NaOH.
In this case is important as behaving in a neutralization products in water HCl + NH3 = NH4Cl NH4Cl + H2O = NH4OH (weak base) + HCl (strong acid) so...

How do you solve for moles by using the molarity and volume of an acid. The only information I have is 25mL HCl. Assume 1g/mL and the molar mass of HCl is 36.48g
V (HCl) = 25 mL (volume) ρ (HCl) = 1 g/ml (density) M (HCl) = 36.5 g/mol (you can`t write 36.48, it`s wrong) n (HCl) - ? (moles) Solution: First...

How many mL of concentrated HCL solution are needed to provide 90.0g of HCL? Concentrated HCL solution is 37.0% HCl by weight and has a density of 1.19 g/mL.
p =m/V 1,19 = 90/V V = 75,63 ml - it's volume of 37% HCL Need to solve a mass of full solution ( x = V(HCL)+(H2O) ), then 75,63...
