I need help solving this:
The grams of protein in 1 cup of soup that has 110 Cal with 7 g of fat and 9 g of carbohydrate.
Express your answer using one significant figure.
Thanks

Are you using the same values I am for grams fat, grams protein, grams carbs?
Total Cal = g fat + g carb + g protein.
110 Cal = (7*9) + (9*4) + (4*g carb)
g carb = (110-63-36)/4 = 2.75 which is rounded to 3.00 and to 1 s.f. is 3 grams. Of course you know that 110 Calories = 110 kcal.
Well, 1 cup of soup is definitely more appetizing than 1 cup of soup jokes! Let's do some math here.
First, we need to figure out how many calories are coming from the fat and carbohydrate. We'll use the information that 1 gram of fat is equal to 9 calories and 1 gram of carbohydrate is equal to 4 calories.
For 7 grams of fat, that gives us 7 grams * 9 calories/gram = 63 calories. And for 9 grams of carbohydrate, that gives us 9 grams * 4 calories/gram = 36 calories.
Now, we have to subtract that total from the total calories in the soup.
110 calories - (63 calories + 36 calories) = 11 calories.
So there are approximately 11 grams of protein in 1 cup of soup! Voila!
To solve this problem, we need to find the grams of protein in 1 cup of soup.
First, we need to determine the energy contribution of the fat and carbohydrate in the soup. Fat provides 9 calories per gram, while carbohydrates provide 4 calories per gram.
The soup contains 7 grams of fat, so the energy contribution from fat is 7 g * 9 calories/g = 63 calories.
Similarly, the soup contains 9 grams of carbohydrates, so the energy contribution from carbohydrates is 9 g * 4 calories/g = 36 calories.
Now, we can calculate the energy contribution from protein. Protein also provides 4 calories per gram.
The total energy content of the soup is given as 110 calories. So, the energy contribution from protein can be calculated as:
110 calories - (63 calories from fat + 36 calories from carbohydrates) = 11 calories.
Since protein provides 4 calories per gram, we can calculate the grams of protein by dividing the energy contribution from protein by 4:
11 calories / 4 calories/g = 2.75 grams of protein.
To express our answer using one significant figure, we round the grams of protein to one decimal place:
2.75 grams of protein ≈ 3 grams of protein (rounded to one significant figure).
Therefore, there are approximately 3 grams of protein in 1 cup of the given soup.
For this one-
The grams of sugar (carbohydrate) in one can of cola if it has 140 Cal and no fat and no protein.
Express your answer using one significant figure.
Is the answer 40 once rounded to sig figs?
Thanks
For the cola drink:
If you're using 4 Cal/g carb, then
140/4 = 35 g carb which I would round to 40 and to 1 s.f. that is 4 x 10^1 or 4E1.
I don't know what 40 once means.
