Answer:

A compound

Explanation:

A compound is chemical entity that is formed when 2 or more elements are joined together in a fixed ratio.

This fixed ratio is simply the numerical values of the numbers of these elements. Take for example in the case of water, one atom of oxygen joins together with two atoms of hydrogen. The fixed ratio here is 1 to 2 or 2 to 1 depending on the reference element.

For example also in methane. The molecular formula of Methane is CH4. The ratio between carbon and hydrogen is 1 to 4 here

Aleks04 [339]

Answer: The molar mass of the given compound is $1.11\times 10^2 g/mol$

Explanation:

In molecular formula of $CaCl_2$ there are two chlorine atoms and one calcium atom.

The atomic mass of the calcium = 40.07 g/mol

The atomic mass of chlorine = 35.5 g/mol

Molar mass of the guven compound is :

$40.07 g/mol + 2\times 35.5 g/mol=111.07 g/mol\approx 1.11\times 10^2 g/mol$

The molar mass of the given compound is $1.11\times 10^2 g/mol$

In nature, the chlorine atom has two isotopic forms, 35Cl and 37Cl. The masses of each form are 34.96885amu (75.76%) and 36.9659

Anni [7]

Answer:

Explanation:

mass avg = ( abundance 1 x mass 1 = abundance 2 x mass 2 )

= ( 75.76% x 34.96885 + 24.24% x 36.9659)

= ( 0.7576 x34.96885 + 0.2424 x 36.9659 )

= ( 26.49241 + 8.960534 )

= 35.45294 amu
