Given:
m (substance) = 20 g
m (Br) = 16 g
To find:
w (Br) -?
To calculate the mass fraction of bromine in a substance, we
we will use the formula:
w (Br) = m (Br) / m (substances), substituting the available data from the problem statement into it.
w (Br) = 16g / 20g = 4/5
w (Br) = 16g / 20g = 0.8
w (Br) = 16g / 20g * 100% = 80%
