There are 200 questions in a 3 h examination. Among 200 questions, 50 are from Mathematics, 100 are from GK and 50 are from Science. Ram spent twice as much time on each Mathematics question as for each other question. How many minutes did he spend on Mathematics questions ?

Calculating the cell emf for Nonstandard condition : A galvanic cell is constructed at 298 K as follows. One half-cell consists of a chlorine gas electrode (i.e. Cl_(2)//Cl^(-) couple) with the partial pressure of Cl_(2) = 0.100 bar and C_(CI-) = 0.100 M . The other half-cell involves the MnO_(4)^(-)//Mn^(2+) couple in acidic solution with C_(MnO_(4)^(-)) = 0.100 M, C_(Mn^(2+)) = 0.100 M , and C_(H+) = 1.00 M . Apply the Nernst equation to datermine the cell potenital for this cell. Strategy: First datermine the overall cell reaction and then calculate the standard cell potential (E_("cell")^(@)) from the standard electrode potenital in Table 3.1. then use the Nernst equation to find the cell potential (E) under cited conditions.

Molarity: A sample of commercial sulphuric acid is 98% H_(2) SO_(4) by mass and its specfic gravity is 1.84 . Caculate the molartiy of this sulburic acid solution. Strategy: The density of a solution (grams per milliliter) is numercially equal to its specific gravity. Thus, the density of the solution is 98% H_(2) SO_(4) by mass. Thus, every 100g of soultuon contains 98g of pure H_(2) SO_(4) . From the mass of H_(2) SO_(4) . we calculate its moles and from the density , we calculate its volume. Finally, we calculate molartity using its definition.

CBSE Class 9 Ultimate Strategy to Score 100 in Maths

The marks obtained by Hare Rama in Mathematics, English and Biology are respectively 93 out of 100, 78 out of 150 and 177 out of 200. Find his average score in percent.

The final marks in mathematics of 30 students are as follows: 53,61,48,60,78,68,55,100,67,90,75,88,77,37,84 58,60,48,62,56,44,58,52,64,98,59,70,39,50,60 Arrange these marks in the ascending order, 30 to 39 one group, 40 to 49 second group etc. Now answer the following: What is the highest score? What is the lowest score? What is the range? If 40 is the pass marks how many have failed? How many have scored 75 or more? Which observations between 50 and 60 have not actually appeared? How many have scored less than 50?
