Answer:

Iron

Explanation:

Given data:

Density of metal = 7.86 g/cm³

Volume = 7.10 cm³

Moles of metal = 1 mol

Metal present = ?

Solution:

D = m/v

m = d×v

m =  7.86 g/cm³ × 7.10 cm³

m = 55.806 g

Number of moles = mass/ molar mass

Molar mass = mass/ number of moles

Molar mass =  55.806 g / 1 mol

Molar mass =  55.806 g/mol

The molar mass of iron is 55.8 so given data is about iron metal.
