Calculate the number of atoms of the 52 moles of Ar
A welding fuel gas contains carbon and hydrogen only. Burning a small sample of it in oxygen gives 3.38 g carbon dioxide, 0.690 g of water and no other products. A volume of 10.0 L (measured at STP) of this welding gas is found to weigh 11.6 g. Calculate (i) empirical formula, (ii) molar mass of the gas, and (iii) molecular formula.
Use the data given in the following table to calculate the molar mass of naturally occurring argon isotopes:-
|Isotope||Isotopic molar mass||Abundance|
