Answer:
4198.97404999
Explanation:
In chemistry, the formula weight is a quantity computed by multiplying the atomic weight (in atomic mass units) of each element in a chemical formula by the number of atoms of that element present in the formula, then adding all of these products together.
Using the chemical formula of the compound and the periodic table of elements, we can add up the atomic weights and calculate molecular weight of the substance.
If the formula used in calculating molar mass is the molecular formula, the formula weight computed is the molecular weight. The percentage by weight of any atom or group of atoms in a compound can be computed by dividing the total weight of the atom (or group of atoms) in the formula by the formula weight and multiplying by 100.
Answer:
0.15cal/g°C
Explanation:
Given parameters:
Mass of copper piece = 35g
Initial temperature = 29°C
Final temperature = 76°C
Amount of heat absorbed = 243cal
Unknown:
Specific heat of copper = ?
Solution:
The specific heat is the amount of heat supplied to a unit mass of substance that causes a 1°C rise in temperature.
Specific heat C, = 
where H is the amount of heat supplied
m is the mass of the copper
T is the temperature
Input the parameters;
C = 
= 0.15cal/g°C
