∙ 8y agoTo find the number of moles, divide the given mass (272g) by the molar mass of the substance. For example, if the substance is water (H2O), the molar mass is approximately 18g/mol. Dividing 272g by 18g/mol gives you approximately 15 moles.
The common octopus weighs 6.6 to 22 lbs, but different species can weight anywhere from 1oz to 150 lbs.
There really isn't an easy way to figure the exact amount of bone in a chicken, because every chicken is a little bit different. However, a general rule of thumb is that when you cut up a whole chicken, there is going to be approximately 40% of the chicken for refuse (that is, portions that cannot be directly eaten). You can use those portions - for example, drumstick bones and rib bones, etc - for chicken stock and flavoring, but they cannot be directly digested. So, by this theory, one pound of bone-in chicken would equal 0.6 pounds (approx. 9.5 oz, or 272g). However, this is not an exact science. And if you are following a recipe that uses bone-in chicken, also keep in mind that bone-in chicken has a longer cooking time, so you will have to adjust your recipe accordingly, otherwise you'll overcook your chicken and it might be tough and dry.
