A sample of metal has a mass of 24.54 g, and a volume of 5.02 mL. What is the density of this metal? g/cm
zmey [24]

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

What is the molar mass of HBR
alexdok [17]

Answer:

Molar mass of bromine is equal to 80.9119

Explanation:

The molar mass of HBr is equal to the sum of atomic weight of  Bromine.

Atomic Weight of hydrogen is equal to 1.00794

Atomic Weight  of Bromine is equal to 79.904

Molar mass of Bromine

= Atomic Weight of hydrogen + Atomic Weight  of Bromine

Molar mass of Bromine  = 79.904 + 1.00794  = 80.9119
