In a compound containing one atom of X for every atom of oxy

In a compound containing one atom of X for every atom of oxygen ,the ratio of masses is 8.58gx per gram of oxygen .identify element X

Solution

Identification of X

one atom of X per atom of Oxygen

molecular formula = XO

ratio of masses (X/O) = 8.58

so,

mass of X = 8.58 x 16 = 137.28 g/mol

Element X = Ba
