Which of these would change the measured relative atomic mass of an element sample in a mass spectrometer?
A mineral contains 0.500 mol of element X with Ar = 58.7. What is the mass of X in the mineral?
Which is the best definition of an isotope?
Neon has isotopes 20 (90.48%), 21 (0.27%), 22 (9.25%). What is Ar to 3 s.f.?
A sample of a chloride salt is analysed and the element’s relative atomic mass is found to be non-integer. Which is the most likely explanation?
A student finds a sample containing 0.50 mol of element Y with Ar 24.0. What mass in grams does the sample have?
Which of the following correctly links Ar, mol and Avogadro’s number?
A sample of element Q weighs 1.00 g and contains only isotope mass 50. How many moles of atoms does it contain? (Ar = mass per mol)
Element X has isotopes 50 (abundance 40%) and 52 (abundance 60%). Which calculation gives Ar?
A student is given Ar for two elements: A = 11.0 and B = 23.0. Which statement is true about the masses of one mole of each element?
Which statement best describes relative atomic mass (Ar)?
