10.00 g of hydrochloric acid reacts with excess calcium to form hydrogen gas and calcium chloride.  What mass of calcium chloride will be formed?

Using periodic table of elements

usually    72.916 gm of HCl    reacts and forms 75.528 gm of CaCl

we can set up a ratio

 

10/72.916  =  x / 75.528     x = CaCl formed = 10.358 gm
