Answer: 3.00 molecules
Explanation:
Given that:
Mass of CO2 = 132.03 grams
Number of molecules of CO2 = ?
Molar mass of CO2 = ?
For the molar mass of CO2: Atomic mass of Carbon = 12; Oxygen = 16
= 12 + (16 x 2)
= 12 + 32 = 44g/mol
Apply the formula:
number of molecules = (mass in grams/molar mass)
N = (132.03 grams/44g/mol)
N = 3.00 molecules
Thus, there are 3.00 molecules of CO2 in 132.03 grams of CO2.
Answer:
The answer to your question is molality = 0.22
Explanation:
Data
molality = ?
mass of glucose = 100 g
molar mass of glucose = 180 g
mass of water = 2.5 kg
Process
1.- Calculate the moles of glucose using proportions
180 g ------------------ 1 mol
100 g ------------------ x
x = (100 x 1) / 180
x = 100 / 180
x = 0.56 moles
2.- Calculate the molality
Formula
molality = moles / mass of solvent
- Substitution
molality = 0.56 / 2.5
- Simplification
molality = 0.22
The answer is; active transport
This means that energy is expended in the process. Because large protein cannot be transported through protein channels in the plasma membrane for being too big, they are transported through endocytosis. This means a vesicle merges with the plasma membrane and forms an invagination that engulfs the protein. The vesicle then encloses with the protein inside and moves into the cell.
