Mass of the water is 2.63 g.
<u>Explanation:</u>
Mass of the water, m = ? g
Temperature, ΔT = 15 °C
Heat absorbed, q = 165 J
Specific heat capacity, c = 4.18 J / g °C
q = m × c × ΔT
Now, we have to find the mass of the water by rewriting the above equation as,
m = 
Now Plugin the above values in the equation as,
m = 
= 2.63 g
So the mass of the water is found as 2.63 g.
A common factor is low pressure system.
Assuming we have 100g, this means that
39.97g Carbon * 1 mol / 12 g = 3.33 mol Carbon
13.41g Hydrogen * 1 mol/1 g = 13.41 mol Hydrogen
46.62g Nitrogen * 1 mol / 14 g = 3.33 mol Nitrogen
Dividing everything by 3.33, we get
1 mol Carbon, 4.03 mol Hydrogen, 1 mol Nitrogen.
Empirical formula is CH4N
<span>The mass of the empirical formula is
12 + 4 + 14 = 30
Since the molar mass is double, we multiply all our subscripts
The molecular formula is C2H8N2
The answers to this question are </span><span>an empirical formula of CH4N</span> and a molecular formula of C2H8N2 .
Answer:
C
Explanation:
cause it looks right and I also studied but wait til someone gives another answer
Gas is the most compressible at room temperature.
