First convert celcius to Kelvin.
20 + 273 = 293K
31 + 273 = 304K
Now we can set up an equation based on the information we have.
V1 = 5
P1 = 365
T1 = 293
V2 = 5
P1 = x
T2 = 304
The equation be:
Now just solve.
1825/293 = 5x/304
Cross multiply.
554800 = 1465x
Divide both sides by 1465
x = 378.7030717 which can then be rounded to 378.7 mmHg
Answer:
Plausible structure has been given below
Explanation:
- Molar mass of
is 44 g/mol and molar mass of
is 18 g/mol
- Number of mole = (mass/molar mass)
4.04 g of =
= 0.0918 moles of
1 mol of contains 1 mol of C atom
So, 0.0918 moles of contains 0.0918 moles of C atom
1.24 g of =
= 0.0689 moles of
1 mol of contain 2 moles of H atom
So, 0.0689 moles of contain
of
or 0.138 moles of
Moles of C : moles of H = 0.0918 : 0.138 = 2 : 3
Empirical formula of hydrocarbon is
So, molecular formula of one of it's analog is
