14. You are calibrating a buret that is graduated to 0.1 mL. The measured volume delivered is 25.31 mL at 24.50°C. The calculated actual volume based on the mass of water is 25.390 mL. IMPORTANT: The actual volume is reported to 2 decimal places since the buret volume is reported to 1/100 of a mL. The buret correction (mL) equals: -0.08 O 0.080 O -0.080 0.08

Can some help me, work through the problem in section (e) using my answers in section (a) trough (d)? I think the wording in section (e) has me a bit confused.
VIII. A primary standard of HCI is sodium carbonate, Na2CO3. A measured mass of solid Na2CO3, mNa2CO3' in grams, is dissolved in water and then titrated with HCI solution using methyl 2 NaCl + CO2 + H2O. orange indicator. The reaction is: Na2CO3 + 2 HCI- Complete the following formulas using the context described above: MHCI × VHCI in mL at the methyl orange endpoint = mNa2CO3 × ( )= mol of Na2CO3 mol of Na2CO3 X (— ( - - )= mol of HCl
The mystery fuel speedster! (Homework ) For fun, you build an explosive car with your little brother by attaching wheels to an empty windshield washer container. To advance it, you add 1.20 ml ( = 0.7915 g/ml) of a liquid but volatile fuel into the container. You close the cap and shake to evaporate the liquid. Finally, you place the car on its wheels, remove the cap and insert a burning wooden rod into the container. A flame suddenly comes out of the car, which is propelled with good speed in front of your little brother surprised, but all upset by the maneuver. The volatile fuel is composed of 37.5% carbon, 12.6% hydrogen and 49.9% oxygen. Its molar mass is approximately 32.0 g/mol. During the reaction, the fuel (gaseous) burns in the presence of gaseous oxygen, and the products of the reaction are carbon dioxide and water, gaseous too. The volume of the windshield washer container used is 4.00 litres. Useful Info: There is 21.0% gaseous oxygen in the air and initial conditions…
You rent a Peugeot in Sarlot France to go see chateau Baynac. Its gas rating is 17.2 km/L. Convert this to miles per gallon using the following conversions; 1 L = 1.06 qts, 4 qts = 1 gal, 1 mile = 1.609 km. (report answer, a space, then units, miles/gallon)
