<u>Answer:</u> The concentration of solute is 0.503 mol/L
<u>Explanation:</u>
To calculate the concentration of solute, we use the equation for osmotic pressure, which is:
where,
= osmotic pressure of the solution = 24 atm
i = Van't hoff factor = 2 (for NaCl)
c = concentration of solute = ?
R = Gas constant = 
T = temperature of the solution = ![25^oC=[273+25]=298K](https://tex.z-dn.net/?f=25%5EoC%3D%5B273%2B25%5D%3D298K)
Putting values in above equation, we get:
Hence, the concentration of solute is 0.503 mol/L
The answer is A. (glaciers, heat and water)
Answer:
1.) The aluminum block
2.) more than the nail it came from
3.) Rust contains iron and oxygen
Explanation:
1.)
Mass, Density, and Volume are related by the following equation;
Mass = Volume*Density
Solving for volume;
Volume = Mass/Density
If Mass is constant then;
Volume ∝ 1/Density ; That is volume and density will be inversely proportional. The larger the volume the smaller the density
2.)
If an iron nail were allowed to rust completely, you should find that the rust weighs more than the nail it came from since Iron combines with oxygen and water from the air to form rust.
3.)
Rust contains iron and oxygen.
Rust is composed or made up of hydrated iron(III) oxides Fe2O.
Answer:
Explanation:
Convection currents are created when the air above your radiator heats and then cools and is then heated again. This process happens continuously whilst you have your heating on and the current moves the heat around the room making it nice and warm and toasty.
