I'm not sure what "mole" is but I am gonna assume molar so "Molar" mass is the mass of a given substance divided by the amount of that substance, measured in g/mol. For example, the atomic mass of titanium is 47.88 amu or 47.88 g/mol. In 47.88 grams of titanium, there is one mole, or 6.022 x 1023 titanium atoms.
have a good day hope this helps
Henri Becquerel is the first scientist who discover evidence of radioactivity.
Maria Curie is one of the most famous scientists in the world who invented the word "radioactivity". She discovered that radioactive materials gave out rays and discovered two elements: polonium and radium, which are extraordinary active.
Answer:
21.182 g
Explanation:
There are about (6.0)(10^23) atoms in one mole of a substance, so the given sample has about 0.333 mol of Cu.
The atomic mass of Cu is 63.546 g/mol, meaning that the answer is about <u>21.182</u><u> </u><u>g</u>
