How many moles of carbon dioxide are there in 211g of carbon dioxide?
211g of carbon dioxide are equal to 4,794 moles.
Why do different proteins have the same relative molecular mass?
Different proteins can have the same relative molecular mass because molecular weight alone does not determine a protein's structure or function. Proteins can vary in amino acid sequence, post-translational modifications, and three-dimensional structure while still having the same molecular mass. Thus, proteins with different compositions and functions can have similar molecular masses.
What is the molecular weight for insulin?
The human insulin protein is composed of 51 amino acids, and has a molecular mass of 5808 Da. Insulin for other species will be somewhat different.

What is the total number of atoms contained in 2.00 moles of helium?
This number is 12,044 280 171 4.10e23.
What happens to the volume of the gas when the number of moles is doubled?
The ideal Gas Law states the following:
pV=nRT
p=pressure [pa]
V=volume [m³]
n=number of moles
R=constant
T=temperature [K]
So, if you multiply the number of moles by 2, and all the other variables are not changed, your volume will also be multiplied by 2.
