Calculate the volume of 0.5m potassium hydroxide that will neutralize 45cm³ of 0.1m tetraoxosulphate(VI) acid solution.
(K=39,O=16,H=1)
In a titration, 10.0 ml of H2SO4 is required to neutralize 0.0400 mol of NaOH. From this data, the [H2SO4] is?

Ravan's dream is to win Tic-Tac-Toe championship.to accomplish this he practices alone at home to learn the strategies of the game . your task is to identify the cell where Ravan should place his third piece so that he wins the game. Assume that each cell in the tic-tac-toe board is marked with a number as shown in the below
tic tac toe
0 1 2
3 4 5
6 7 8
input:
The first line of input contain two space-seperated integers representing the cells where Ravan has placed his first two pieces
output:
output should be a single line integer representing the cell where ravan should place his final piece
explanation
sample Output 1 :
ravan's first two moves are 0 and 1 so he not 2 to win the game .because it will complete the first row so the out put is 2
sample Output 2 :
ravan's first two moves are 0 and 3 so he not 6 to win the game .because it will complete the first row so the out put is 6
When a ball naturally floats in a pool filled with mercury (density 13600 kg/m° the buoyancy force on the ball is 2224 N. If a force of 1200 N is required to force the ball
completely under water, what is the volume of the ball?
If the density of water is 1,00 g/cm° and atmospheric pressure is 1,013 x 105 Pa, the depth in water (in m) where the absolute pressure is four times atmospheric
pressure, is equal to:
ball with a diameter of 20,00 cm is placed in water with 75% of its volume above the surface of the water. The buoyant force of the water on the ball is…?
