Answer:
Explanation:
Henry's law states that the amount of dissolved gas in a liquid is proportional to its partial pressure above the liquid
number of moles of cyclopropane = 1.84 g / 42.08 g/mol = 0.044 mol
number of mole of water = 1010000 g / 18.02 g/mol = 56048.83 mol
mole fraction of cyclopropane = mole of cyclopropane / ( mole of water + mole of cyclopropane) = 0.044 mol / 56048.87 = 7.85 × 10⁻⁷
P cyclopropane = k henry × mole fraction of cyclopropane = 4273 atm × 7.85 × 10⁻⁷ = 0.00335 atm
b) number of cyclopropane molecules present in each cubic centimeter = ( 0.044 mol / 1010) × 6.022 × 10 ²³ / 1000 cm³ = 2.623 × 10 ¹⁶ molecules in cm³
Explanation:
First, we will calculate the molar mass of 
as follows.
Molar mass of = 
= 78 g/mol
So, when 2 mol of 
burns, then heat produced = 6542 KJ
Hence, this means that 2 molecules of 
are equal to 
of burns, heat produced = 6542 KJ
Therefore, heat produced by burning 5.5 g of =
= 228.97 kJ
= 228970 J (as 1 kJ = 1000 J)
It if given that for water, m = 5691 g
And, we know that specific heat capacity of water is 4.186 
.
As, Q = 
228970 J = 
Thus, we can conclude that the final temperature of the water is 
.
A)poor metals
B)Nobel gases
C)metalloids
D)transition metals
E)alkali metals
