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

multiple allele inheritance is traits controlled by more than 2 alleles (ex: pigeons having 3 alleles of one gene govern their feather color).

the total distance that martina travels that day is

(distance from home to mom's office) plus (distance from mom's office to school)

plus (distance from school to library) plus (distance from library to friend's house)

plus (distance from friend's house to martina's house).

(we don't know what any of these distance actually is.)
