CBSE Class 9 Ultimate Strategy to Score 100 in Maths

Jayant scored 33 marks in English, 38 marks in Mathematics, 36 marks in Sociology, 28 marks in Hindi and 34 marks in Economics. The maximum marks a students can score in each subject is 100. How much percentage did Jayant get in this exam?

Hydocarbons, obtained from coal and coal tar and from oil and gas wells, are organic compounds composed entirely of C and H. A 0.1647 g sample of a pure hydrocarbon was burned in a C - H combustion train to produce 0.4931 g of CO_(2) and 0.2691 g of H_(2)O . Determine the masses of C and H in the sample and the percentages of these elem ents in the hydrocarbon. Strategy: Step 1 . Use the observed mass of CO_(2) to determine the mass of C in the original sample using the information that there is 1 mol of C atoms in each mole of CO_(2) . Step 2 . Use the observed mass of H_(2)O to calculate the mass of H in the original sample using the fact that there are 2 mol of H atoms in each mole of H_(2)O . (We can also calculate the mass of H by subtracting the mass of C from the mass of sample. However, it is good experimental practice, when possible, to base both on experimental measurements as this would help to check for errors in the anlysis of calculation.) step 3 . Calculate the percentages by mass of each element in turn, using the relationship % Element = ("Gram of element")/("Gram of sample") xx 100 %
