The density of gasoline is 7.30 × 102 kg/m3 at 0°C. Its average coefficient of volume expansion is 9.60 × 10-4 (°C)-1, and note that 1.00 gal = 0.00380 m3.
(a) Calculate the mass of 10.4 gal of gas at 0°C.
(b) If 1.000 m3 of gasoline at 0°C is warmed by 20.0°C, calculate its new volume.
1.08
Incorrect: Your answer is incorrect.
Your response is within 10% of the correct value. This may be due to roundoff error, or you could have a mistake in your calculation. Carry out all intermediate results to at least four-digit accuracy to minimize roundoff error. m3
(c) Using the answer to part (b), calculate the density of gasoline at 20.0°C.
Your response is within 10% of the correct value. This may be due to roundoff error, or you could have a mistake in your calculation. Carry out all intermediate results to at least four-digit accuracy to minimize roundoff error. kg/m3
(d) Calculate the mass of 10.4 gal of gas at 20.0°C.
kg
(e) How many extra kilograms of gasoline would you get if you bought 10.4 gal of gasoline at 0°C rather than at 20.0°C from a pump that is not temperature compensated?
kg
