There are three possible reading frames for a mature mRNA, each of which can be translated into a protein. If the mature mRNA is 522 bases long, then there are 174 amino acids in the protein.
The number of amino acids in a protein is determined by the number of codons in the mrna. A codon is a sequence of three nucleotides that corresponds to a specific amino acid. There are four different nucleotides, so there are 64 possible codons (4^3). However, only 61 of these codons actually encode for an amino acid, as three of them are stop codons that signal the end of the protein. Therefore, the number of amino acids in a protein is equal to the number of codons in the mRNA divided by three. In this case, the mRNA is 522 bases long, so there are 522/3 = 174 amino acids in the protein.
