Consider a pool that is 12.0 meters wide and 30.0 meters long. Each raindrop has a volume of 0.05 mL and 250 raindrops fall per square meter per minute. This is how water accumulates in the pool per hour.
What is 270 liters of water?
Step 1: Calculate the total area of the pool:
Area = 12.0 m × 30.0 m= 360.0 m2
Step 2: Calculate the number of raindrops falling on the pool per minute: 250 raindrops/m2 × 360.0 m2 = 90,000 raindrops/min
Step 3: Calculate the volume of water accumulated per minute: 90,000 raindrops/min × 0.05 mL/raindrop = 4500 mL/min
Step 4: Convert minutes to hours (60 minutes = 1 hour): 4500 mL/min × 60 min/hour = 270,000 mL/hour
Step 5: Convert milliliters to liters (1000 mL = 1 L): 270,000 mL/hour ÷ 1000 = 270 L/hour
Answer: 270 liters of water accumulate in the pool per hour.
This is the electron configuration of Mo4+ (molybdenum 4+ ion). You may use noble gas configuration.
