What exactly is an explosion

1 answer:

6 0

An explosion is a sudden release of enormous energy, being released all at once, particularly from a trapped container. The enormous amount of energy being released expands rapidly, more than the air can adjust around them, which makes the sound you hear and the fast light that you see is the energy being released.

You have a 150mL sample of an aqueous solution at 25C. It contains 15.2mg of an unknown nonelectrolyte compound. If the solution

Serga [27]

The molar mass of the compound:

If the solution has an osmotic pressure of 8.44 torr, then the molar mass of the unknown non-electrolyte is 223.14 g.

What is osmosis?

Osmosis is defined as the flow of solvent molecules through semi-permeable membrane.
Osmotic pressure is the pressure applied to stop the flow of solvent molecules.
It is a colligative property that means osmotic pressure depends on the number of solute particles .

Therefore,

π $V=inRT$ ( for electrolytes)

Where, π= Osmotic pressure

i = Van 't Hoff factor

n= moles

R= Gaseous constant = 62.363577 L torr $mol^{-1}K^{-1}$

T= Temperature

V= Volume of solution

Given:

T= 298K

V= 150 mL= 0.150 L

Given mass of unknown electrolyte= 15.2 mg = 15.2 x $10^{-3}$ g

Osmotic pressure= 8.44 torr

Molar mass= ?

For non-electrolytes:

πV = n RT

πV= $\frac{m}{M}$ RT

Calculations:

Putting the given values in the formula:

8.44 x 0.150 =15.2 x $10^{-3}$ / M x 62.36 x 298

1.266 = 282.5/M

M = 282.5/1.266

M = 223.14 g

Therefore,

The molar mass of the unknown non-electrolyte is 223.14g.

What is the change in vapor pressure when 74.60 g fructose, C6H12O6, are added to 185.5 g water (H2O) at 298 K (vapor pressure o

Vlad1618 [11]

Answer:

Vapor pressure of pure water: 3.1690 kPa

Explanation:

Vapor pressure is P=0.955(3.1690)=3.0263 kPa

Change in vapor pressure : 3.169-3.0263=0.142 kPa

If the caffeine concentration in a particular brand of soda is 2.01 mg/oz, drinking how many cans of soda would be lethal? assum

dedylja [7]

1 can of soda has 12 ounces * 2.01 mg/oz = 24.12 mg of caffeine.

1 gram = 1000 mg

10 grams x 1000 mg = 10,000 mg

Divide total mg by mg per can:

10,000 / 24.12 = 414.59 cans

Round to 415 cans
