A particular brand of gasoline has a density of 0.737 g/mL at 25 ∘C. How many grams of this gasoline would fill a 15.4gal tank?

Compute 4659¯0−214¯00. Round the answer appropriately.
Express your answer numerically using the proper number of significant figures. 
Convert 15.4 gallons to liters then to mL. 1 gallon = 3.785 L.
Then mass = volume x density 
Can you clarify the numbers? I don't know what the "dash" at the top means.

15.4 converted to ml is 5827.36 can you help me with the rest plz

58273.6

NVM I GOT IT. THE ANSWER IS 42947.6432

Thanks. for helping. i forgot to put the grams

15.4 x 3.785 = 58.289 L or
58289 mL.
Then m = v x d = 58289 x 0.737 = 42959 g which I would round to 4.3E4 grams.
