Answer: B) 13.25 cm

Explanation: A centimeter ruler is used to measure the lengths of objects and the lengths are recorded to two decimal places.

The given numbers are 13.2 cm, 13.25 cm, 130 cm and 132 cm. 13.2 cm has only one decimal place, 13.25 cm has two decimal places, 130 and 132 cm have zero decimal places.

So, the only correct choice is 13.25 cm as it has two decimal places and so its more precised.

What is the average isotopic mass of an element that has the following abundances in nature? Isotopic mass: X20 X22 X23 Abundanc
Paladinen [302]

Answer: 20.2

Explanation:

Mass of isotope 1 = 20

% abundance of isotope 1 = 90.5% = \frac{90.5}{100}=0.905

Mass of isotope 2 = 22

% abundance of isotope 2 = 8.0% = \frac{8}{100}=0.08

Mass of isotope 3 = 23

% abundance of isotope 3 = 1.5% = \frac{1.5}{100}=0.015

Formula used for average atomic mass of an element :

\text{ Average atomic mass of an element}=\sum(\text{atomic mass of an isotopes}\times {{\text { fractional abundance}})

A=\sum[(20\times 0.905+(22\times 0.08)+(23\times 0.015]

A=20.2

Therefore, the average atomic mass of the element is 20.2.
