The definition of mass percent follows:Mass percent 100% 100%For example, suppose a solution is prepared by dissolving 1.0 g of sodiumchloride in 48 g of water. The solution has a mass of 49 g (48 g of H 2 O plus1.0 g of NaCl), and there is 1.0 g of solute (NaCl) present.
Rule of thumb calculation for steak calories per serve is roughly 170 calories per 100 grams. Calories in steak is based on a 3.5 ounce serving or 100 grams. Calories are approximate and can alter with fat marbling of the meat. Frying in fat will add lots of calories. You should grill meat and trim fat from the cut.
It is very common for a steak to be four ounces, six ounces, eight ounces or even more. A typical T-bone steak, for example, can weigh 16 ounces and provide approximately 704 calories, 30 grams of fat, almost 12 grams of saturated fat and 102 grams of protein, according to the USDA. A filet mignon, or beef tenderloin steak (shown on the label), is usually much smaller and leaner.
