I have a chemistry question. Which states calculate the number of moles present in 980 kg of copper sulphide. I got 980 divided 95.012 which equals 10.249759444212024 but the answer is 10.2 times 10 to the power of three?

Remember you have to convert 980 kg into grams:
980 X 1000=980,000grams
980,000 / 95.012=10.3 X10^3 moles present in 980 kg.
