{"ops":[{"insert":"1. calculate the number of atoms of oxygen present in 8g of CO2 ? What would be the weight of CO having the same number of oxygen atoms?\n2.Potassium bromide (KBr) contains 32.9% by mass potassium. If 6.40g of bromine reacts with 3.6g of potassium, calculate the number of moles of potassium which combines with bromine to form KBr.\n3.The molecular mass of an organic compound is 78 g and its percentage composition is Carbon: 92.4% and hydrogen: 7.6%. Determine the molecular formula of the compound\n4.A compound has the composition Na-14.31%, S-9.97%, H-6.22% and O-69.5%.\n5. Calculate the molecular formula assuming that all the hydrogen in the compound is present in combination with oxygen as water of crystallization. The molecular mass is 322\n6. 25. Butyric acid contains carbon, hydrogen and oxygen. 4.2 mg sample of butyric acid is completely burnt to give 8.45 mg of CO2 and 3.46 mg of water. What is the mass percent of each element in the acid?\n"}]}
