A mineral contains 0.500 mol of element X with Ar = 58.7. What is the mass of X in the mineral?
Neon has isotopes 20 (90.48%), 21 (0.27%), 22 (9.25%). What is Ar to 3 s.f.?
A student is given the abundance x of isotope mass 100 and (100-x)% of mass 102. If Ar measured = 101.2, what is x?
An unknown element Z has Ar measured as 40.0. Which is the most likely identity from the periodic table?
Copper has isotopes 63 (69.2%) and 65 (30.8%). Which Ar value matches these abundances?
An element has two isotopes: mass 10 (20% abundance) and mass 11 (80% abundance). What is the relative atomic mass (Ar) of the element?
Which statement best describes relative atomic mass (Ar)?
Which procedure would you use to calculate the mass of 3.00 × 10^24 atoms of element with Ar 39.1?
If sample A contains only isotope 14 (100%) and sample B contains natural mixture giving Ar 14.01, which statement is true?
Which change would NOT affect the calculated relative atomic mass (Ar) of an element?
A chemist has 6.02 × 10^23 atoms of an element whose Ar = 63.5. What is the mass of this mole in grams?
