1 cup is 8 oz . So a cup of chopped sirloin should be 8 ounces.
There are 8 liquid ounces of chopped mushrooms, or for that matter, anything, in a single cup. If you are referring to ounces in weight, then it depends on the density of the specific mushrooms.
Well lets see. You fill up a cup measure with chopped tomatoes 3 times. Or... since a cup weighs approximately 8 ounces, 3 cups would be 24 ounces. Since cans usually come in 8, 15 and 28 ounces, you could use 3 8 ounce cans, or a 28 ounce can. Whether or not you use all of the 28 ounce can would depend on the need for exactness in your recipe.
That is approximately 6 ounces
that would be 28 ounces
