To calculate density, you need to know the volume of the object as well. Without the volume of the blocks, it's not possible to determine the density just from the mass.
To calculate the weight in pounds, you would convert the mass from kilograms to pounds. 1 kilogram is approximately 2.205 pounds. Therefore, if the mass is 146 kilograms, the weight would be approximately 321.77 pounds.
Uranium, i think, its also has 92 protons and 92 electrons
Uranium, atomic number 92, has several isotopes, and 238U is just one of them. Remember that a nucleon is one of the particles that make up the nucleus of an atom, and that means a proton or a neutron. In the case of this isotope of uranium, it has the 92 protons we'd expect for uranium, and it has 146 neutrons in its nucleus along with those protons. That's 238 necleons in the nucleus if 238U. Wikipedia has more information on uranium and on the nucleon, and links are provided.
The weight of uranium can vary depending on the specific isotope and form (e.g., natural uranium, enriched uranium). The most common isotope, uranium-238, has a density of about 19.1 grams per cubic centimeter.
hi there, have you asked a question, what are 146 pounds in kilograms? well, the exact figures are 66.2244904 hey hey wait a second before leaving the page note down my blog address, so in future if you have some questions, do ask directly. dilgar12.wordpress.com see ya raja
