4.88x10^20 H2O2 molecules
Answer:
The molality of the solution is 0.3716 mol/kg
The number of moles of solute is 0.0157 mol
The molecular weight of the solute is 129.30 g/mol
The molar mass of the solute is 129.32 g/mol
Explanation:
m (molality of the solution) = ∆T/Kf = (43.17 - 40.32)/7.67 = 0.3716 mol/kg
Number of moles of solute = molality × mass of solvent in kilogram = 0.3716 × 0.04219 = 0.0157 mol
Molecular weight of solute = mass/number of moles = 2.03/0.0157 = 129.3 g/mol
When Kf = 7.66 °C.kg/mol
Molar mass = 2.03 ÷ (2.85/7.66 × 0.04219) = 129.32 g/mol
Answer:
- Nucleus Function - Controls and regulates the activity of the cell.
- Ribosome builds proteins.
- A vesicle structure is kinda like a sac filled with a fluid of sorts.
- Rough ER has ribosomes attached to the cytoplasmic side of the membrane.
- Golgi apparatus kinda looks like a "stack of peta bread"
- Golgi apparatus functions as a factory in which proteins received from the ER are further processed and sorted for transport to their eventual destinations
The cytoskeleton of a cell is made up of microtubules, actin filaments, and intermediate filaments.
- The smooth endoplasmic reticulum functions in many metabolic processes. It synthesizes lipids, phospholipids as in plasma membranes, and steroids.
- The mitochondria produced energy/ATP
- Mitochondria have a double membrane arrangement that separates the organelle into four distinct compartments
- The cytosol contains an organized framework of fibrous molecules that constitute the cytoskeleton
Reactants are the substances that undergo changes and the new substance created from it is called products.
