A quantity commonly used to express the concentration of a solution is called the molarity of the solution. It gives the number of moles n of solute that dissolves in a volume V of the solution in liters (L), or in formula form: ...
Determine the number of moles of NaOH required to neutralize the acetic acid in the 100.0 mL of vinegar. Mole-Mole Relationship: To determine the number of moles of one reactant required to react with another reactant during a chemical reaction can be determ...
Total moles of OH−=Moles from NaOH+Moles from Ba(OH)2=0.015+0.80V Step 5: Calculate the Final VolumeThe total volume of the solution after adding Ba(OH)₂ will be:Total Volume=50.0mL+V(in mL) Step 6: Set Up the Molarity EquationWe want the final molarity of OH⁻ to be ...
Moles of NaOH required=3×Moles of H3PO4=3×0.04=0.12mol Step 3: Calculate the final concentration of NaOH in the solutionWe need to find the final concentration of NaOH in the 300 ml of the final solution. Let V1 be the volume of 0.2 M NaOH solution to be added. The total volume...
step 3- Number of moles formed per min, perml of initial solution?Step - 4 - conversion to correct units = enzyme activity?硬算的话,难道是1 unit/mol/unit0.5 unit/mol/unit0.33 unit/mol/unit
1) to change % to concentration For H2SO4: 4.74*10/MWH2SO4 = 0.48 mol L-1 For NaOH: 48.5*10/MWNaOH = 12.13 mol L-12) 0.48mol of 21mL H2SO4 is eq to 0.01008 mol3) since acid to alkali ratio is 1:2, therefore moles of NaOH needed is 0.02016 mol4) therefore volume needed...
Related to this Question How many mL of 0.343 M HI are needed to titrate 58.4 mL of 0.652 M NaOH to the equivalence point? How many milliliters of 0.0850 m NaOH are required to titrate 50.0 mL of a solution that contains 1.85 g of HCl per lite...
40 grams of {eq}NaOH {/eq} in 1000 mL of water equals how many equivalent(s) of {eq}OH^- {/eq}? a. 23 b. 17 c. 3 d. 1 e. 40 Equivalents: For bases as well as acids, the count of moles of hydroxide or hydronium ion liberated upon dissolution ...
The moles of CO2 was calculated at .00233 mol. The experiment was also a success because it was found that the heat released from combining and eating pop rocks with soda would not kill the consumer unless it was consumed in very high doses. The combination is not dangerous because it ...
In a titration-based reaction the neutralization of the acid with the base is often referred to as the "equivalence point". Answer and Explanation: Phosphoric acid is a triprotic acid. Therefore it will require three times the number of moles of NaOH for ne...
