1. Pure substances cannot be separated into any other kinds of matter, while a mixture is a combination of two or more pure substances.

2. A pure substance has constant physical and chemical properties, while mixtures have varying physical and chemical properties (i.e., boiling point and melting point).

3. A pure substance is pure, while a mixture is impure.

An element consists of two isotopes. The abundance of one isotope is 95.72% and its atomic mass is 114.9041 u. The atomic mass o

meriva

Answer:

d. 114.8 u

Explanation:

The formula for the calculation of the average atomic mass is:

$Average\ atomic\ mass=(\frac {\%\ of\ the\ first\ isotope}{100}\times {Mass\ of\ the\ first\ isotope})+(\frac {\%\ of\ the\ second\ isotope}{100}\times {Mass\ of\ the\ second\ isotope})$

Given that:

<u>For first isotope: </u>

% = 95.72 %

Mass = 114.9041 u

<u> For second isotope: </u>

Since the element has only 2 isotopes, so the percentage of second is 100 - first percentage.

% = 100 % - 95.72 % = 4.28 %

Mass = 112.9043 u

Average Mass = ?

Thus,

$Average\ atomic\ mass=\frac {95.72}{100}\times {114.9041}+\frac {4.28}{100}\times {112.9043}\ u$

<u>Average atomic mass = 114.8 u</u>
