Question

a solid mass of 25 g is mixed with 60 g of a solution. A chemical reaction takes place and a gas produced. the final mass of the mixture is 75 g. what is the mass of the gas released

Answer 1

According to the conditions of the matter, 25 g of solid is mixed with 60 g of solution. therefore, in theory, 85 g of the mixture should have been formed. however, in practice, 75 g of the mixture was formed.that is, the missing mass corresponds to the gas:

25+60= 85

85-75=10 gr gase
