Question

A student obtains a 1.00 mole sample of titanium metal and a 1.00 mole sample of silver metal. Which of the

Answer 1

The silver sample has more mass than the titanium sample.

Further explanation

Given

1 mole titanium

1 mole silver

Required

mass and number of atoms

Solution

The mole is the number of particles(molecules, atoms, ions) contained in a substance  

1 mol = 6.02.10²³ particles

Moles can also be determined from the amount of substance mass and its molar mass

n = mass : molar mass

mass = n x molar mass

1 mole titanium ⇒ mass = 47,867 u

1 mole silver ⇒ mass = 107,8682 u

Both metals have the same number of atoms as they have the same number of moles i.e. 6.02.10²³

While the mass of silver is greater than the mass of titanium
