The specific heat of a gas is found to be 0.075 calories at constant volume and its formula Wt . is 40. the atomicity of the gas is……………. .
Atomicity is a new term on me. I googled it an found that it is a synonym in chemistry for valence but I don't get the connection. Can you define atomicity as you are using it?
To find the atomicity of the gas, we need to first understand the concept of specific heat at constant volume and its relationship with the atomicity of the gas.
Specific heat (symbol: c) is the amount of heat required to raise the temperature of a substance by 1 degree Celsius. It can be measured at constant volume (cv) or constant pressure (cp).
The formula to calculate the specific heat at constant volume is given by:
c = (Wt * k) / (n * m)
Where:
- c is the specific heat at constant volume
- Wt is the formula weight of the gas
- k is a constant value (specific to the system of units used)
- n is the number of molecules of the gas
- m is the mass of the gas
In this case, the specific heat at constant volume (cv) is given as 0.075 calories, and the formula weight (Wt) is 40. We need to find the atomicity, which is represented by 'n'.
Rearranging the formula, we get:
n = (Wt * k) / (c * m)
Since the value of k is not provided, we can't directly calculate the atomicity of the gas. The constant 'k' depends on the units used for measuring specific heat, so it varies.
However, if we assume k = 1 (in some unit system), we can calculate an approximate value for the atomicity:
n = (40 * 1) / (0.075 * m)
To find the accurate atomicity of the gas, we would need to know the mass (m) of the gas or the value of the constant 'k' used in the specific heat calculation.
