The isotopes of Madeupium (Ma) and their abundance in nature are shown below. Which is the most likely estimate of what the atomic mass is close to? Ma-74 (74.333 - 85%)

Ma-75 (74.999 - 10%)

Ma-76 (75.700 - 5%)

A. 74 g

B. 75 g

C. 76 g

A = 74 g

Explanation:

Given data:

Ma-74 (74.333 - 85%)

Ma-75 (74.999 - 10%)

Ma-76 (75.700 - 5%)

Atomic mass close to = ?

Solution:

1st of all we will calculate the average atomic mass.

Average atomic mass = (abundance of 1st isotope × its atomic mass) +(abundance of 2nd isotope × its atomic mass) + (abundance of 3rd isotope × its atomic mass) / 100

Average atomic mass  = (85×74.333)+(10×74.999)+(5×75.700) /100

Average atomic mass =  6318.305 +749.99+ 378.5 / 100

Average atomic mass= 7446.795/ 100

Average atomic mass = 74.467 amu

The average atomic mass is closer to the 74 g.

answer; i believe that the correct answer is (a) potassium(k)

the formula for the conversion of temperature from degree celsius to kelvin is:

the sample of water at is converted to kelvin temperature by using the above formula as:

on comparing the two samples of water at or we can say that at and at respectively. the difference between the temperatures of two samples of water is:

hence, one can say that the sample of water at is greater than the sample of water at by .
