Chemistry problem: given: serving size 0.5 oz, 4g fat/ serving, 140 mg sodium/serving. a) box has net weight of 8oz how many crackers per box? i got 96. b) if you ate 10 crackers how many ounces of fat are you consuming? i got 0.23 ounces. c) how many grams of sodium are used to prepare 50 boxes of crackers. I got 112g. the answers are in the back, and the first 2 i got right, however they have 110g for part c. I don't understand how.

I read your problem last evening. Nowhere in the problem do you state the mass of a cracker or the number of crackers in a serving. If your answer of 96 crackers is correct, I calculate 6 crackers to make a serving and I obtained 112 grams of sodium to make 50 boxes also. You need to make your posts easier to read by capitalizing i and beginning all sentences with a capital letter. Texting type is ok for text messages but here, where you are asking for help, you need to be clear with your writing and questions.

To solve part (c) of the problem, we need to calculate the total grams of sodium in 50 boxes of crackers.

Given:
- Serving size: 0.5 oz
- Sodium per serving: 140 mg
- Net weight of one box: 8 oz

To calculate the total grams of sodium in 50 boxes, we need to find the number of servings in 50 boxes and then multiply it by the sodium content per serving.

First, let's find the number of servings in 50 boxes:
- Given that each box has a net weight of 8 oz, we can divide the total weight of 50 boxes (8 oz/box) by the serving size (0.5 oz):

Number of servings in 50 boxes = (8 oz/box) / (0.5 oz/serving) = 16 servings/box * 50 boxes = 800 servings

Now, let's calculate the total grams of sodium in 50 boxes by multiplying the sodium content per serving (140 mg) by the number of servings (800 servings) and converting it to grams:

Total grams of sodium = (140 mg/serving) * (800 servings) * (1 g/1000 mg) = 112 g

According to your calculations, you also obtained 112 g. However, the answer key states 110 g, which suggests there might be a discrepancy. It's possible that the answer key contains a rounding error or there might be some additional information given in the problem that you haven't mentioned.
