What element has a mass of 235?
uranium
The mass number is commonly cited in distinguishing among the isotopes of an element, all of which have the same atomic number (number of protons) and are represented by the same literal symbol; for example, the two best known isotopes of uranium (those with mass numbers 235 and 238) are designated uranium-235 ( …
Is one mole equal to Avogadro’s number?
Avogadro’s number is an absolute number: there are 6.022×1023 elementary entities in 1 mole. This can also be written as 6.022×1023 mol-1. The mass of one mole of a substance is equal to that substance’s molecular weight.

What is the atomic mass of oxygen quizlet?
The element oxygen consists of three naturally occurring isotopes: 16O, 17O, and 18O. The atomic mass of oxygen is 16.0 amu.
What is the formula for molecular mass?
Add up the mass of all the atoms to find the molecular weight. Molecular weight = ∑((Atomic Mass of Element) n x (# of atoms of that element) n) Round the answer as necessary, using significant digits.
What is the difference between molar mass and molecular weight?
Molar mass and molecular weight are often confused, but their values are very different. Molar mass is the mass of one mole of a substance, while molecular weight is the mass of one molecule of a substance. One mole is the number of particles, such as atoms, molecules, ions or electrons, in a substance.
How do you find the molecular mass of an element?
Molecular mass may be calculated by taking the atomic mass of each element present and multiplying it by the number of atoms of that element in the molecular formula. Then, the number of atoms of each element is added together.
