Determine the specific heat of a material if a 35-9 sample absorbed 96 ) as it was heated from 293 Kto 313 K.
Norma-Jean [14]

This is an incomplete question, here is a complete question.

Determine the specific heat of a material if a 35 g sample absorbed 96 J as it was heated from 293 K to 313 K.

Answer : The specific heat of a material is, 0.137 J/g.K

Explanation :

Formula used to calculate the specific heat of a material is:

q=m\times c\times (T_2-T_1)

where,

q = heat absorbed = 96 J

m = mass of sample = 35 g

c = specific heat capacity of material = ?

T_1 = initial temperature = 293 K

T_2 = final temperature = 313 K

Now put all the given values in the above formula, we get:

96J=35g\times c\times (313-293)K

c=0.137J/g.K

Therefore, the specific heat of a material is, 0.137 J/g.K

How many atoms of magnesium are in a 134 gram sample of magnesium?
ryzh [129]
No. of moles in 134g of Mg, n=134/24 =5.58 moles
No. of atoms = n* Avogadro number
                     = 5.58 X 6.022 X 10^23
                      =33.60 X 10^23 atoms
