Calculate the osmotic pressure of a solution containing 1.502 g of (nh4)2so4 in 1 l at 36.54 degrees celcius. (the gas constant is .08206 latm/molk. the molar mass of (nh4)2so4 is 132.16)

0.2886 atm is the osmotic pressure of a solution.

Explanation:

Osmotic pressure of solution =

Concentration of the solution = c

Mass of the ammonium sulfate = 1.502 g

Moles of ammonium sulfate =

Volume of the solution = 1 L

Concentration of the solution:

Temperature of the solution ,T= 36.54°C = 309.69 K

R = universal gas constant = 0.08206 L atm/mol K

0.2886 atm is the osmotic pressure of a solution.

answer:

technetium is the most reactive. this is followed by silver. the least reactive out of these three elements is strontium.
