Magnesium has three common isotopes.
sladkih [1.3K]

Answer:

Explanation:

percentage abundance of third isotope = 100 - ( 78.900 + 10.009)

= 11.091 %

Atomic mass

24.1687 x .789 + 25.4830 x .10009 + 24.305 x .11091  

19.069 + 2.5506 + 2.69566

= 24.3153 amu

What is the amount of heat energy absorbed when 36 grams of ice at -20oC is melted to water at 0oC?
Ulleksa [173]

Answer:

Q = 1461.6 J

Explanation:

Given data:

Mass of ice = 36 g

Initial temperature = -20°C

Final temperature = 0°C

Amount of heat absorbed = ?

Solution:

specific heat capacity of ice is 2.03 j/g.°C

Formula:

Q = m.c. ΔT

Q = amount of heat absorbed or released

m = mass of given substance

c = specific heat capacity of substance

ΔT = change in temperature

ΔT = T2 - T1

ΔT =  0°C - (-20°C)

ΔT = 20°C

Q = 36 g ×2.03 j/g.°C×20°C

Q = 1461.6 J
