During a titration the concordant titres are 23.45, 23.55 and 23.50 cm3. Which value should be used for calculations and why?
In a precipitation experiment 10.0 cm3 of 0.100 mol/dm3 AgNO3 is mixed with 10.0 cm3 of 0.100 mol/dm3 NaCl. What is the concentration of Ag+ (in mol/dm3) remaining if 0.00800 mol of AgCl precipitates? (Assume total volume 20.0 cm3)
A sample contains 0.250 g of dissolved NaCl in 50.0 cm3. What is the concentration in g/dm3 and in mol/dm3? (Mr NaCl = 58.44)
If 0.0150 mol of MgCl2 is dissolved to make 250 cm3 of solution, what is the molar concentration?
You have 0.250 dm3 of 0.120 mol/dm3 CaCl2. How many grams of CaCl2 (Mr = 110.98) are present?
In a reaction 25.0 cm3 of 0.200 mol/dm3 HCl reacts exactly with 15.0 cm3 of NaOH. What is the concentration of NaOH in mol/dm3? (HCl + NaOH ? NaCl + H2O)
In a titration, 25.0 cm3 of H2SO4 requires 30.0 cm3 of 0.100 mol/dm3 NaOH to reach the endpoint for H2SO4 + 2 NaOH ? Na2SO4 + 2 H2O. What is the concentration of H2SO4 in mol/dm3?
A student finds concentration by evaporating 25.0 cm3 of solution and obtaining 0.450 g of solute. What is concentration in g/dm3?
A mass of 4.20 g of an acid (Mr = 60.0) is dissolved in water to give 250 cm3. What is the concentration in mol/dm3?
A student finds the mean titre is 23.50 cm3 with a burette uncertainty of ±0.10 cm3 and a pipette uncertainty of ±0.02 cm3. Which is the best combined uncertainty to quote for the titre in cm3?
In an experiment you need 0.0200 mol of Na2CO3. How many cm3 of 0.100 mol/dm3 solution do you use?
