Question

Atoms of different elements also have different average masses, just like kernels and marbles. Use the mass values from a periodic table to answer the following questions. Please use the precision of the values in the periodic table link to determine the correct number of significant figures for your answer. (a) What is the relative mass of one atom of H to one atom of F? matom of H matom of F = WebAssign will check your answer for the correct number of significant figures.

(b) What is the relative mass of one mole of H to one mole of F? mmole of H mmole of F = WebAssign will check your answer for the correct number of significant figures.

(c) What is the relative mass of 1.5 moles of Mg to 1.5 moles of Ag? mmole of Mg mmole of Ag = WebAssign will check your answer for the correct number of significant figures.

Explanation / Answer

Atomic mass of Hydrogen = 1.00794 g
Atomic mass of Fluorine = 18.998403 g

relative mass = 1.00794/18.998403 = 0.05305

For part b) is the same because the atomic mass is g/mol, so 1 mol weights that atomic mass, so the relative mass is the same

For part c):
Mg = 24.305 g/mol
Ag = 107.8682 g/mol

mass of Mg = 1.5 * 24.305 = 36.4575 g
mass of Ag = 1.5 * 107.8682 = 161.8023 g

relative mass = 36.4575/161.8023 = 0.2253

Hope this helps
