Atomic mass is the answer!!
Explanation: An elements atomic number won’t be able to change
Answer: The approximate molecular mass of the polypeptide is 856 g/mol
Explanation:
To calculate the concentration of solute, we use the equation for osmotic pressure, which is:
Or,
where,
= osmotic pressure of the solution = 4.19 torr
i = Van't hoff factor = 1 (for non-electrolytes)
Mass of solute (polypeptide) = 0.327 g
Volume of solution = 1.70 L
R = Gas constant = 
T = temperature of the solution = ![26^oC=[273+26]K=299K](https://tex.z-dn.net/?f=26%5EoC%3D%5B273%2B26%5DK%3D299K)
Putting values in above equation, we get:
Hence, the molar mass of the polypeptide is 856 g/mol
Answer:
If you mean the number of atoms in 8g of oxygen, it's 3.011 x 10^23 atoms.
Explanation:
Convert the grams to moles. 8 grams of oxygen is 0.5 moles. Then multiply the number of moles by Avogadro's number: 6.022 x 10^23.
Answer:
The Bronsted-Lowery acid is H2O
The Bronsted-Lowery base is CO3
The conjugate acid is HCO3
The conjugate base is OH
Explanation:
Molocules that lose a hydrogen in a reaction act as an acid, and those that recieve one act as a base.
Answer:
C) 979 dg
Explanation:
1 Decagram = 0.01 Kilogram, and 1 kilogram = 100 Decagram.
