- 0.0715 gal = _____ c m 3 2.27 x 10 4 mL = _____ g a larrow_forwardConvert 761 mi to kilometers (1 m = 1.094 yd; 1 mi = 1760 yd). O 1470 km O 1220 km 696 km O 832 km O 4.70 x 104 kmarrow_forwardA 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_forward
- 1. 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_forwardPredict the products for the following reaction (ignore balancing): O Sn3(PO4)2 (aq) + KNO3(aq) O Sn3(PO4)4 (s) + K (s) + NO₂(g) O No reaction O SnPO4 (s) + KNO3(aq) O Sn3(PO4)2 (s) + KNO3(aq) Consider the combustion of octane (C8H18), given the following unbalanced equation: O 227 g tin(II) nitrate (aq) + potassium phosphate (aq) O 4.54 g O 226 g O 79.8 g O 45.4 g C8H18 + O2 → What is the mass of H₂O (MM = 18.02 g/mol) will be generated by the complete combustion of 159.7 g of octane in excess oxygen? CO₂ + H₂O [unbalanced] 6.6 6.67arrow_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
- The speed of light is 3 x 108 m/sec Assume: 1.6 km/mile 1.If the earth is close to Mars, we are roughly 50 million miles apart. How many minutes will it take for us to communicate with astronauts on Mars? 2.When we are at opposites in our orbits, we are close to 200 million miles apart. How many minutes will it take for us to communicate with astronauts on Mars?arrow_forwardConvert 1.0 gallon to milliliters 1 gal = 3.785 Larrow_forwardA piece of copper has a volume 300 L. What is the mass of the sample, in units of grams? Fill in the blank red squares. The numerator and denominator of a conversion unit must represent equivalent quantities. For example, 1 L equals 1000 cm3, but not 8.8 g Cu.arrow_forward
