Determine the osmotic pressure (atm) of an aqueous sugar solution with a

Chemistry

Answer:

61 atm

Explanation:

You can calculate osmotic pressure using the following equation:

π = <em>i </em>MRT

In this equation,

-----> π = osmotic pressure (atm)

-----> <em>i</em> = van't Hoff's factor

-----> M = molarity (M)

-----> R = Ideal Gas Constant (0.08206 atm*L/mol*K)

-----> T = temperature (K)

The van't Hoff's factor is the amount of ions the substance dissociates into. Since sugar does not dissociate, this value is 1. After converting Celsius to Kelvin, you can plug the values into the equation and simplify.

<em>i</em> = 1                                 R = 0.08206 atm*L/mol*K

M = 2.5 M                      T = 25 °C + 273.15 = 298.15 K

π = <em>i </em>MRT

π = (1)(2.5 M)(0.08206 atm*L/mol*K)(298.15 K)

π = 61 atm

Answer:

<h3>A Werewolf</h3>

___________

Poem with Compound Words

------------------------------------------

whenever there's a full moon,

I cannot overlook,

some alterations in my ways,

and changes in my look.

my werewolf hair grows everywhere,

my werewolf teeth get long,

my eyesight gets much keener and

I'm muscular and strong.

I get to roam around outside,

the moonlight makes me howl,

these otherworldly sound effects

mean I am on the prawl.

I see the moon is round and full,

I'm moonstruck by the sight,

I've made some telltale changes-so, you'd best stay in tonight.
