How many moles of copper (1) bromide can be produced by the synthesis of 18.75 g copper
according to the following reaction: 2 Cu + Br2 --> 2CuBr
A)18.75 mol CuBr
B)O .59 mol CuBr
C)2.00 mol CuBr
D)0.30 mol CuBr

The answer to your question is the letter D.

Explanation:

Data

moles of CuBr = ?

mass of Cu = 18.75 g

Balanced chemical reaction

                  2 Cu  +  Br₂  ⇒   2 CuBr

Process

1.- Convert the mass of Cu to moles

Atomic mass = 63.55 g

                         63.55 g 1 mol

                          18.75 g x

                           x = (18.75 x 1)/63.55

                           x = 0.295 moles

2.- Use proportions to find the moles of CuBr

                       2 moles of Cu 2 moles of CuBr

                       0.295 moles of Cu  x

                        x = (0.295 x 2) / 2

                        x = 0.295 moles of CuBr ≈ 0.30 moles
