3.0.2640 g of sodium oxalate is dissolved in a flask and requires 30.74 ml of potassium permanganate to titrate it to turn pink end point. the equation for this reaction is: 5na, c,o4+ 2kmno,+ 8h, so 2mnsog+ k, so,+ 5 na, so,+ 10co2+ 8h2o a) how many moles of sodium oxalate are present in the flask?

0.001970 moles of sodium oxalate are present in the flask.

Explanation:

Mass of sodium oxalate = m = 0.2640 g

Molar mass of sodium oxalate = = 134 g/mol

Moles of compound:n

Number of moles of sodium oxalate:

0.001970 moles of sodium oxalate are present in the flask.

the molecules move in straight line until they collide with each other or with the walls of the container. collisions are perfectly elastic; when two molecules collide, they change their directions and kinetic energies, but the total kinetic energy is conserved.

explanation:

answer

i think the answer is a) as air pressure in an area increases, the density of the gas particles in that area decreases.

hope it
