Question
A scientist uses 2 kilograms of sodium every 20 minutes during an experiment.If the experiment lasted 1 hour, how many total grams of sodium did they use?A)60B)600C)60,000D)6,000
Solution
First, we need to determine how many 20-minute intervals are in 1 hour. Since there are 60 minutes in an hour, there are 60/20 = 3 intervals in an hour.
Next, we know that the scientist uses 2 kilograms of sodium every 20 minutes. Since there are 3 intervals in an hour, the scientist would use 2*3 = 6 kilograms of sodium in an hour.
Finally, we need to convert kilograms to grams. Since 1 kilogram is equal to 1,000 grams, 6 kilograms is equal to 6*1,000 = 6,000 grams.
So, the scientist used 6,000 grams of sodium in an hour. The answer is D) 6,000.
