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?

See your post above.

To find out how many grams of gasoline would fill a 15.4-gallon tank, we need to convert gallons to milliliters and then use the density of the gasoline to calculate the mass.

First, let's convert the 15.4 gallons to milliliters:

1 gallon = 3.78541 liters (exact conversion)
1 liter = 1000 milliliters (exact conversion)

So, 15.4 gallons is equal to:
15.4 gallons * 3.78541 liters/gallon * 1000 milliliters/liter = 58124.544 milliliters (approximately)

Now that we have the volume in milliliters, we can use the density of the gasoline to calculate the mass:

Density = Mass / Volume

Given that the density of the gasoline is 0.737 g/mL, and the volume we calculated is 58124.544 milliliters, we can rearrange the equation to solve for mass:

Mass = Density * Volume

Mass = 0.737 g/mL * 58124.544 mL ≈ 42856.226848 g

Therefore, approximately 42856 grams of gasoline would fill a 15.4-gallon tank.
