What do you want an answer to?
Answer:
4.88 g / cm³
Explanation:
Density of a substance is given by the mass of the substance divided by the volume of the substance .
Hence , d = m / V
V = volume
m = mass ,
d = density ,
From the question ,
The mass of the metal = 24.54 g
The volume of the metal = 5.02 mL
Hence , by using the above formula ,and putting the corresponding values , the density is calculated as -
d = m / V
d = 24.54 g / 5.02 mL
d = 4.88 g /mL
The unit 1mL = 1 cm³
Hence ,
d = 4.88 g / cm³
Answer:
Molar mass of bromine is equal to 
Explanation:
The molar mass of HBr is equal to the sum of atomic weight of Bromine.
Atomic Weight of hydrogen is equal to 
Atomic Weight of Bromine is equal to 
Molar mass of Bromine
= Atomic Weight of hydrogen + Atomic Weight of Bromine
Molar mass of Bromine
