Hemoglobin has a molecular mass of 64 500 u. Find the mass (in kg) of one molecule of hemoglobin.
Thanks for your help, but I figured this one out on my own.
You're welcome! I'm glad you figured it out on your own. However, just for the sake of completeness, let me explain how to calculate the mass of one molecule of hemoglobin.
To find the mass of one molecule of hemoglobin in kilograms, we need to convert the given molecular mass from unified atomic mass units (u) to kilograms (kg).
We know that 1 atomic mass unit is approximately equal to 1.66 x 10^-27 kilograms.
So, to convert 64,500 u to kilograms, we can use the following calculation:
64,500 u * (1.66 x 10^-27 kg/u) = 1.072 x 10^-22 kg
Therefore, the mass of one molecule of hemoglobin is approximately 1.072 x 10^-22 kilograms.
