15.0 mm = 15/10 = 1.5 cm
1.20 m = 1.2 x 100 = 120 cm

Volume = length x width x height = 120 x 1.5 x 5 = 900 cm3

What is the osmotic pressure of a solution made by dissolving 55.0 g of glucose, C6H12O6, in enough water to form 800.0 mL of so
Stels [109]

Answer:

The osmotic pressure is 8.85 atm

Explanation:

Step : Data given

Mass of glucose = 55.0 grams

Volume of water =800.0 mL

Temperature = 10.0 °C

Step 2: Calculate moles glucose

Moles glucose = mass glucose / molar mass glucose

Moles glucose = 55.0 grams / 180.156 g/mol

Moles glucose = 0.305 moles

Step 3: Calculate osmotic pressure

π = iMRT  

⇒ with π = the osmotic pressure = TO BE DETERMINED

⇒ with i = the van't Hoff factor for glucose = 1

⇒ with M = the concentration = moles / volume = 0.305 moles / 0.800 L =0.381 M

⇒ with R = the gas constant = 0.08206 L*atm*mol¨K

⇒ with T = the temperature = 10.0 °C = 283 K

   

 π = 1* 0.381 *0.08206 * 283

 π = 8.85 atm

 

The osmotic pressure is 8.85 atm

Explain why a city that receives 10 hours more light each day has colder average temperatures. Explain
Anestetic [448]

Explanation:

This would be similar to how the poles work in the North and South. Due to their placement, they recieve much more sun light than the rest of the Earth since we rotate horizontally. However, their placement also makes them farther from the sun than the rest of Earth, therefore not receiving as much heat.

How many atoms are in 1.00 moles of He
olchik [2.2K]

Answer:

1.00 mole of He have 6,02x10^{23} atoms.

Explanation:

To solve this exercise it is important to know the definition of Avogadro's number

Avogadro's number is the proportional factor that relates the molar mass of a substance to the number of elementary units (atoms, molecules, particles, ions, electrons) that constitute it and its magnitude is equal to 6.022 140 857 × 10²³

One mole of helium we have 6,02x10^{23} atoms.
