With these questions you need to consider all the information they ve given you in this case they tell you that your stibnite sample weighs 500Kg convert this to g which should give you 500000 and that 5% of this stibnite is Sb2S3 You can therefore immediately work out the mass of Sb2S3 5% of 500000 to be 25000g So now you have mass of Sb2S3 Remember that your goal is to figure out
