Answer:

0.06538 g

Explanation:

Moles of the element = Mass of the element/ Atomic mass of the element

Given,

Moles of Zn = 1.0 x 10⁻³ mol

Atomic mass of Zn = 65.38 amu (atomic mass unit)

Mass of Zn = moles of Zn x atomic mass of Zn = 1.0 x 10⁻³ x 65.38  = 65.38 x  10⁻³ g

Expressing 65.38 x  10⁻³as a decimal we have,

Mass of Zn = 0.06538 g
