The density of gasoline is a 0.7025 g/mL at 20 degree C. What is the mass of 2 gallons(ignore sig figs on given volume) of gasoline? (1 qt = 0.9463 L, 4 qt = 1 gal)
What is the mass of a 1.82-L sample of a liquid that has a density of 0.921g/mL?
gasoline has a density of 0.74 g/mL. how many milliliters of gasoline have a mass of 2.4 kg?
Gasoline has density of 0.74 g/mL. How many milliliters of gasoline have a mass of 0.60 kg? Express your answer to two significant figures and include the appropriate units.
Retailers purchase gasoline by weight so they get a constant amount of gasoline per dollar (as long as the price is constant). We buy gasoline by volume. The enthalpy of combustion of 1.00 L of gasoline is –3.539 x 10 4 kJ at 15.6 o C when gasoline has a density of 0.73722 g/mL. What would the enthalpy of combustion of 1.00 L of gasoline be at 32.2 o C when gasoline has a density of 0.72210 g/mL?
The complete combustion of octane, C8H18, a component of gasoline, proceeds as follows: 2C8H18(l)+25O2(g)→16CO2(g)+18H2O(g) Relevant volumetric equivalencies 1 gal = 3.785 L 1 L = 1000 mL part C Octane has a density of 0.692 g/mL at 20∘C. How many grams of O2 are required to burn 17.0 gal of C8H18? Express the mass in grams to three significant digits.
The concentration of Cu2+ ion in a sample of spring water is 5.3 ppm. What mass of Cu2+ ion is present in 6.5 L of this pring water, which has a density of 1.00 g/mL? O 2.6 g 0 0.068 g O 0.034 g O 0.34 g
A gaseous sample of a compound has a gas density of 0.647 g/L at 694 torr and 20 °C. What is the 4. molar mass of this compound? If this compound contains only nitrogen and hydrogen, and is 82.2% nitrogen by mass, what is its molecular formula? 5. What is the density in g/L of neon gas at STP?
Isooctane, C8H18, is the component of gasoline from which the term octane rating derives. A. Write a balanced equation for the combustion of isooctane to yield CO2 and H2O. B. Assuming that gasoline is 100% isooctane, the isooctane burns to produce only CO2 and H2O, and that the density of isooctane is 0.792 g/mL, what mass of CO2 in kilograms is produced each year by the annual US gasoline consumption of 4.6 x 10^10 L? C. What is the volume...
A compact car gets 31.4 miles per gallon on the highway. If gasoline contains 65.9% carbon by mass and has a density of 0.7355 g/mL, determine the mass (in kg) of carbon dioxide produced during a 500. mile trip.
