Question

b. mgbr₂ 184.11g/mol

1. what do we use to convert between grams and moles (g→mol or mol→g)?

Explanation:

To convert between grams and moles, the molar mass of a substance is used. The molar mass (in g/mol) is the mass of one mole of a substance. For example, if we have \(n\) moles of a substance with molar mass \(M\) (g/mol), the mass \(m\) (in grams) is given by \(m = n\times M\). Conversely, if we have a mass \(m\) of a substance, the number of moles \(n\) is \(n=\frac{m}{M}\).

Answer:

Molar mass.
