To solve this problem you need to convert 10 g of caffeine to the number of cans using appropriate conversion factors.
First you convert grams of caffeine to milligrams of caffeine using the conversion factor 1000 mg / 1 g
Next you convert milligrams of caffeine to ounces of soda using the conversion factor 1 oz / 2.99 mg
Finally you should convert ounces of soda to cans of soda using the conversion factor 1 can / 12 oz
So your answer will be
10 g caffeine × (1000 mg / 1 g) × (1 oz / 2.99 mg) × (1 can / 12 oz) = 279 cans of soda
