Answer:
b) 5.87 E23 molecules
Explanation:
∴ mm SO3 = 80.066 g/mol
⇒ molecules SO3 = (78.0 g)(mol/80.066 g)(6.022 E23 molec/mol)
⇒ molec SO3 = 5.866 E23 molecules SO3
D. It has almost no hydrogen ions, therefore it is very basic.
Answer:

Explanation:
A protein is a long chain of amino acids linked together by amide groups.
