Calculate the average atomic mass of Mg if the naturally occurring isotopes are Mg - 24, Mg - 25 and Mg - 26. Their masses and a

bundances are as follows:
Mg - 24 relative atomic mass = 23.985 amu % abundance = 78.70%
Mg - 25 relative atomic mass = 24.986 amu % abundance = 10.13%
Mg - 26 relative atomic mass = 25.983 amu % abundance = 11.17%

Answer:

24.309

Explanation:

mass×percentage+.. = average amu

23.985×78.7/100+24.986×10.13/100+25.983×11.17/100

to three decimal places

=24.309

If the following weights have masses of 2, 4, 6 and 8 kg,
Marrrta [24]

Answer:

8 kg mass

Explanation:

As we can see in the image the weight of mass 8 kgs has a large surface area as compared to the surface area of other masses. In general, it has been observed that a wide surface area has more surface particle for heat conduction. Hence, the rate of heat transfer is directly proportional to the surface area of heat conducting surface. Thus, the larger the surface area, the faster is the rate of heat conduction.

Hence, weight of mass 8Kg wil transfer heat a fast rate.
