C2H4 n 0,4, M 28, V 22,4, m
It looks like you are providing the molecular formula for ethylene (C2H4) along with some additional information. Let's break this down:
C2H4: This is the molecular formula for ethylene, which is an alkene.
n: This typically represents the number of moles. The density, molar mass, and volume information can be used to find n.
M (Molar Mass): The molar mass of C2H4 is approximately 28 g/mol (which you have provided).
V (Volume): It seems that you mentioned 22.4 L, which is the volume that one mole of an ideal gas occupies at standard temperature and pressure (STP).
m: This usually denotes mass.
To calculate the mass (m) of n moles of ethylene, you would use the formula:
\[ m = n \times M \]
If we take \( n = 0.4 \) moles and \( M = 28 \, \text{g/mol} \):
\[ m = 0.4 \, \text{mol} \times 28 \, \text{g/mol} \] \[ m = 11.2 \, \text{g} \]
So, the mass (m) of 0.4 moles of C2H4 is 11.2 grams.
If you are looking for additional information or have a specific question relating to these values, feel free to elaborate!
