Answer:
26.85 grams
Explanation:
The formula for mole calculations is number of moles = given mass/gram-formula mass.
The number of moles is given to us, which is 0.125.
The gram formula mass of SnSO4 is about 214.77.
Plug in the values we have into the equation. It should look like this:
0.125 = x / 214.77
Solve for x by multiplying 214.77 and 0.125. The answer should be about 26.85 grams.
Answer:
π = 29.3 atm
Explanation:
The osmotic pressure π is given by
π = i MRT, where i=Vant Hoff factor =2 for NaCl ( 2 moles ions/mol NacL)
M = molarity
R = 0.0821 Latm/molK
T = temperature K
Assuming density of solution is 1 g/mL
M= 35 g/58.44 gmol / 1 L = 0.60 M
π = 2.0 x 0.60 mol/L x 0.0821 Latm/kmol x 300K = 29.3 atm
I believe the answer is 80. I am not sure
