Part A Gasoline has density of 0.74 g/mL. How many milliliters of gasoline have a mass of 2.3 kg?
Express your answer to two significant figures and include the appropriate units.

How do the energy differences between the higher energy levels of an atom compare with the energy difference between the lower energy level of the atom

100 grams of molten lead (600°c) is used to make musket balls. if the lead shot is allowed to cool to room temperature (21°c), what is the change in entropy (in j/k) of the lead? (for the specific heat of molten and solid lead use 1.29 j/g⋅°c; the latent heat of fusion and the melting point of lead are 2.45 × 104 j/kg and 327°c, respectively.)

If 15 drops of ethanol from a medical dropper weight 0.60g, how many drops does it takes from a dropper to dispense 1.0ml of ethanol? the density of ethanol is 0.80g/ml
