The answer for that kind of question depends on many things. location, how many people will inhabit the home, whether or not the home is a vacation home or a full time home. etc. P.S. I do not believe that this has anything to do with chemistry
Answer:
1.45 mol
Explanation:
Given data
- Volume of the gas (V): 8.77 L
- Temperature of the gas (T): 20 °C
- Pressure of the gas (P): 3.98 atm
Step 1: Calculate the absolute temperature (Kelvin)
We will use the following expression.
Step 2: Calculate the number of moles (n) of the gaseous sample
We will use the ideal gas equation.
I don't know what model you're referring to so I can't answer the question. However, upon researching, I found a similar problem. I posted it as an attached picture. Looking at the model, the amount of grams a herbivore eat each day corresponds to the arrow pointing inwards. Since the label says 4.0 g,
<em>the answer is 4 g per day</em>.
The properties of elements are determined by their group/family. Usually, its the area they are located on the periodic table. The valence electrons also determine reactivity, etc.
Answer:
0.25 mole of NO2 contains 0.25 mole 'N'
one mole contains 6.023 x 10 ^23 atoms
0.25 mole II------------------------------>?
= 0.25 x 6.023 x10^23 = 1.5 x 10^23 atoms
