I cant see the picture but
heeeerrrrreeeee
Answer:
D. Halogens
Explanation:
All elements in these groups have 7 valence electrons, meaning their electronegativity is the highest among the elements.
The answer to this question would be: too low
Molar mass would be determined by the number of mol and the mass of the object. Mass wouldn't be influenced by the temperature, but number of mol is. Using ideal gas formula of PV=nRT you can conlude that the amount of mol(n) is inversely related to the temperature (T).
If the temperature is higher than it supposed to be, then the amount of mol would be lower than it supposed to be.
I think this question is a true statement :)
Answer:
30.0g/mol
Explanation:
Step 1: Given data
- Pressure (P): 1 atm (standard pressure)
- Temperature (T): 273.15 K (standard temperature)
Step 2: Calculate the moles of the gas
We will use the ideal gas equation.
Step 3: Calculate the molar mass of the gas
4.16 × 10⁻³ moles correspond to a mass of 0.125 g. The molar mass of the gas is:
