Riboflavin is one of the B vitamins. It is also known as vitamin B6 and is made up of carbon, hydrogen, nitrogen, and oxygen atoms. When 10.00 g of vitamin B6 is burned in oxygen, 19.88 g of CO2 and 4.79 g of H2O are obtained. Another experiment shows that vitamin B6 is made up of 14.89% N. What is the simplest formula for vitamin B6? The answer should be C17H20N4O6.
What is the pH of a solution in which we have added 40.0 mL of 0.100 M NaOH to 100.0 mL of a 0.100 M solution of acetic acid in a titration. Assume volumes are additive.
An aerosol spray can with a volume of 270 ml contains 3.0 g of propane gas as propellant. what is the pressure in atms if the can is 20 degrees celsius?
Compute the volume of CO 2 and water vapour produced and the volume of oxygen remaining, when 20.0 dm 3 of propane reacts with 120.0 dm 3 of oxygen. All gas volumes are measured at the same temperature and pressure.
