It's 1976 and you are throwing a fondue party! You need to heat 800.0 mL of vegetable oil to 375 F (190.0°C) using an ethanol burner. Assuming a perfect transfer of heat from the burner to the oil, what mass of ethanol (C2H5OH (I)) is required? Assume your kitchen is at SATP (25 C), vegetable oil has a density of 0.920 g/ml and the specific heat capacity of vegetable oil is 2.00J/g*C. Note, this is a combustion reaction! The enthalpies of formation of CO2(g), H2O(g), and C2H5OH() are -393.5, -241.8, and -277.6 kJ/mol, respectively. O 20.04 g O 6.2 g O 12.5 g O 9.06 g O 17.1 g

Density is a measurement that compares the amount of matter an object has to its volume. An object with much matter in a certain volume has a high density. Density helps us predict whether something will float. In this video, the density of oil is assessed by adding food color to the oil above water.
