How do you calculate the amount of CuS and Cu2S in an ore sample given a known sample amount and amount of impurity?

Copper metal can be prepared by roasting copper ore, which can contain cuprite (Cu2S) and Copper (II) sulfide. Cu2S + O2 -> 2Cu + So2
CuS + O2 -> Cu + SO2 Suppose an ore sample contains 11.0% impurity in addition to a mixture of CuS and Cu2S. Heating 100.0 g of the mixture produces 75.4 g of copper metal with a purity of 89.5%. What is the weight percent of CuS in the ore? The weight percent of Cu2S? Clicked enter too fast, sorry.

How do you calculate tip for server?
The custom varies from one country to another. There is sometimes a conventional percentage of the total amount that is given.
How do you calculate density when given mass?
If you only know mass, you don't have enough information to calculate density.You also need to know the volume of the piece that has that mass.Once you have both of those numbers, the density is(Mass) divided by (Volume)of the same sample.

this totally depends on the amount of total chlorine given by the source water and the contaminents and or cross connections.
How do you calucate percentage?
The simple way to calculate percentage is to divide the given amount by the total amount and then multiply the answer by 100 to get the percentage of the given amount in respect of the total amount
