Fat: 1 gram = 9 calories, Protein: 1 gram = 4 calories, Carbohydrates: 1 gram = 4 calories, Alcohol: 1 gram = 7 calories
From the question given above, a bottle of beer contains 15
grams of carbohydrate, 0 grams of fat, 1 gram of protein and 15 grams of
alcohol.
15 g of carbohydrate = 15 x 4 = 60 calories
0 g of fat = 0 calories
1 g of protein = 1 x 4 = 4 calories
15 g of alcohol = 15 x 7 = 105 calories
60 + 0 + 4 + 105 = 169
Therefore a bottle of beer contains 169 calories.
Water is better solvent for salt as compared to oil because water is a polar solvent. The water molecules are tend to attract each other and other polar molecules also because of their polarity. The oil molecules are non polar hence, they will not attract to any other polar molecules. Therefore, water is a better solvent for salt as compared to oil.
