Read each question carefully and use the Factor Label Method (dimensional analysis) to solve the problems. Show all your work, including conversion factors, and ensure your final answer has the correct units and significant figures.
1. Convert 75.0 kilometers per hour (km/h) to meters per second (m/s).
2. A reaction requires 0.500 moles of a reactant. If the molar mass of the reactant is 150.0 g/mol, how many grams of the reactant are needed?
3. The density of gold is 19.3 g/cm³. To convert this to kg/m³, you would multiply by the conversion factor for mass and for volume.
4. If a car travels at a speed of 60 miles per hour, its speed in feet per second is approximately . (Hint: 1 mile = 5280 feet, 1 hour = 3600 seconds)
5. Which of the following is the correct setup to convert 2.5 liters to milliliters?
2.5 L * (1 mL / 1000 L)
2.5 L * (1000 mL / 1 L)
2.5 L / (1000 mL * 1 L)
2.5 L / (1 mL / 1000 L)
6. A car travels at a speed of 85.0 km/h. How many feet does the car travel in 3.00 minutes? (Given: 1 km = 0.6214 miles, 1 mile = 5280 feet)
7. A chemist needs 250. mL of a solution. If the solution's density is 1.15 g/mL, and it contains 15.0% solute by mass, how many grams of solute are in the solution?
8. The Factor Label Method is also known as dimensional analysis.
