Molecular mass is measured in daltons or atomic mass units (same thing); molar mass is measured in grams. The number is the same, but the unit is different.
First balance the equation:
2Al + 3Br2 = Al2Br6
From this, you can see that you need 2 mol of Al to make 1 mol of Al2Br6, so you need 4.86 mol of Al to answer the question.
For biological systems, yes - though you also need the ribosome present to actually translate the RNA into a protein (that's where the synthetic enzymes are actually found).
To clarify the previous answerer: most proteins have hundreds-to-thousands of amino acid residues. There are 20 amino...
1 mole of anything contains 6.023 x 10^23 pieces (atoms or molecules); this is called Avogadro's number, and you just have to memorize it.
1 mole of a pure element weighs the same in grams as the element's atomic weight in daltons. 1 mole of a pure compound weighs the same in grams as the...
