If we burn 3 moles of carbon in air (as per the equation), what mass (in grams) of carbon dioxide will be produced? What volume will this gas occupy at standard temperature and pressure?

So firstly, we assume that the oxygen is in excess (i.e. the amount of oxygen reacting won't limit the amount of carbon that can react), so we know that exactly 3 moles of carbon will be burnt. Then, from...
