An alloy of copper and aluminium is prepared from 65.6 g of Cu and 423.1 g of Al. Calculate the mass percent of each component in this solid solution. Strategy: The mass precentage of a component of a solution is define as: Mass% of a component =`("Mass of the component in the solution")/("Total mass of the solution")xx100%`

An alloy of copper and aluminium is prepared from 65.6 g of Cu and 423

1.	An alloy of copper and aluminium is prepared from 65.6 g of Cu and 423.1 g of Al. Calculate the mass percent of each component in this solid solution. Strategy: The mass precentage of a component of a solution is define as: Mass% of a component =`("Mass of the component in the solution")/("Total mass of the solution")xx100%`
Answer» The data tell us that the total mass of the solution is 65.6 g of `Cu+423.1 g` of `Al=488.7 g` of solution and that there is `65.6 g` of Cu in the solution. Therefore: Mass percent of `Cu=(65.6 g Cu)/(488.7 g soln)xx100%` `=13.4%` Mass percent of `Al=(100%)-(13.4%)` `=86.6%`
