A chemist has 6.02 × 10^23 atoms of an element whose Ar = 63.5. What is the mass of this mole in grams?
Copper has isotopes 63 (69.2%) and 65 (30.8%). Which Ar value matches these abundances?
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 effect do isotopes have on chemical reactions under ordinary conditions?
Given the abundances: isotope A mass 79 (49.7%), isotope B mass 81 (50.3%). What is Ar of bromine (to 2 d.p.)?
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 calculation finds the percentage abundance of isotope X if Ar = 10.2 and isotopes are 10 (x%) and 11 (100-x%)?
Which value is the relative atomic mass (Ar) of chlorine if chlorine consists of 75.77% 35Cl (mass 35) and 24.23% 37Cl (mass 37)?
Element X has isotopes 50 (abundance 40%) and 52 (abundance 60%). Which calculation gives Ar?
A sample contains 0.120 g of an element with Ar = 24.0. How many moles of atoms does the sample contain? (Ar = g per mol)
