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.

What is the difference between sample and sample size?
a sample is a sample sized piece given... a sample size is the amount given in one sample
What is Einstein's equation that us used to calculate the amount of energy produced from a given amount of mass?
E = mc^2
Can a entire population be measured not just a sample?
Yes it can; given that the population number is reasonable and it can be done in a reasonable amount of time.
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.
What is the difference between sample and sample size?
a sample is a sample sized piece given... a sample size is the amount given in one sample
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
How do you calculate atoms nitrogen and oxygen?
To calculate the number of atoms in a sample of nitrogen or oxygen, you first need to know the amount of substance in moles (given in the question or calculated from the sample's mass and the molar mass of the element). Then, you can use Avogadro's number (6.022 x 10^23) to convert moles into the number of atoms. This value represents the number of atoms in one mole of a substance.
How do you use avagardos constant?
Avogadro's constant (6.022 x 10^23) is used to convert between the number of particles (atoms, molecules, ions) and the amount of substance (moles) in a sample. You can use Avogadro's constant to calculate the number of particles in a given amount of substance or to determine the amount of substance from the number of particles.
Can the same urine sample be tested twice for drugs?
Only a small amount is used for any given test so a sample could be tested many times.
How is the formula derived in getting the original amount given the rate and the new amount?
I would take the equation to calculate the new amount, and solve it for the original amount.
What is Einstein's equation that us used to calculate the amount of energy produced from a given amount of mass?
E = mc^2
How do you calculate Interest rate if loan amount and monthly payments and loan amount is given?
17k 300 per month
What is the atomic weight used for?
You can use atomic weight to calculate the number of atoms in a given sample of an element. # g of sample element x (6.02 x 1023 / atomic weight in grams) = # of atoms
Can a entire population be measured not just a sample?
Yes it can; given that the population number is reasonable and it can be done in a reasonable amount of time.
How many molecules in aluminum phosphate?
To calculate the number of molecules in aluminum phosphate, we need to know the mass of the sample. Given the mass of aluminum phosphate, we can use Avogadro's number (6.022 x 10^23 molecules/mol) to calculate the number of molecules in the sample.
A sample of iron has a volume of 10 dot 0 mL The density of iron is 7 dot 87 gmL Which is the correct expression to calculate the mass of the sample using dimensional analysis?
To calculate the mass of the sample using dimensional analysis, you would use the expression: mass = volume × density Substitute the given values for volume (10.0 mL) and density (7.87 g/mL) into the expression to calculate the mass of the iron sample.
