- 0.0715 gal = _____ c m 3 2.27 x 10 4 mL = _____ g a larrow_forwardZinc ore (zinc sulfide) is treated with sulfuric acid, leaving a solution with some undissolved bits of material and releasing hydrogen sulfide gas. If 10.8 g of zinc ore is treated with 50.0 mL of sulfuric arid (density 1.153 g/mL), 65.1 g of solution and undissolved material remains. In addition, hydrogen sulfide (density 1.393 g/L) is evolved. What is the volume (in liters) of this gas?arrow_forward7. Carry out the following conversions: 556 ml to liters O 0.556 L 556 L 55.6 Larrow_forward
- A car’s rate of fuel consumption is often measured in miles per gallon (mpg). Determine the conversion factor between miles per gallon and the SI unit of meters per cubic decimeter (1 gallon =3.785 dm3 , and 1 mile = 1609.344 m).Express 30.0 mpg in SI units.arrow_forwardConvert 35 m³ to liters. 3.5 × 10-2 L 3.5 L 3.5 × 10² L 3.5 × 104 Larrow_forwardConvert 761 mi to kilometers (1 m = 1.094 yd; 1 mi = 1760 yd).

- Gas is sold for $1.299 per liter in Toronto, Canada. Your car needs 10.00 gallons. How much will your credit card be charged in Canadian dollars? (1 gallon = 3.785 L) $49.17 O $52.17 O $67.15 O $36.79arrow_forward1. Write a balanced chemical equation, including physical state symbols, for the combustion of liquid octane into gaseous carbon dioxide and gaseous water. 2. Suppose 0.480kg of octane are burned in air at a pressure of exactly 1atm and a temperature of 19.0°C . Calculate the volume of carbon dioxide gas that is produced. Be sure your answer has the correct number of significant digits. Larrow_forwardSuppose you have a car which gets 51 miles per gallon of gasoline in the city. Suppose you take the car to Canada. Then you fill it up at a gas station in Canada. How many kilometers should the car be able to drive on city streets on 1.7 liters of gasoline? (Note: 1 mile = 1.609 km, 1 gallon = 3.78541 L)arrow_forward
