A0.105-g sample of x2 contains 8.92x1020 molecules. the compound mx3 consists of 54.47% x by mass. what are the identities of m and x, and what is the correct name for mx3?

The element X is chlorine.

The element M is Ytterium.

Ytterium (III) chloride is the correct name for

Explanation:

Molecules of

Moles of

n = 0.001481 mol

Mass of

Molar mass of

M = 70.87 g/mol

Atomic mass of X =

X is a chlorine atom.

The compound consists of 54.47% X by mass.

M' = Molar mass of compound

Percentage of X in compound = 54.47%

M' = 195.16 g/mol

Atomic mass of M = a

a = 88.86 g./mol

The element M is Ytterium.

Ytterium (III) chloride is the correct name for
