Answer:
The molecular formula of the compound is .
Explanation:
Let the molecular formula of the compound is .in
Molar mass of compound = 180 g/mol
Number of carbon atom = x
Number of hydrogen atom = y
Number of oxygen atom = z
Atomic mass of carbon = 12 g/mol
Atomic mass of hydrogen = 1 g/mol
Atomic mass of oxygen = 16 g/mol
Percentage of element in compound :
Carbon :
x = 46
Hydrogen :
y = 12
Oxygen:
z = 5.99 ≈ 6
The molecular formula of the compound is .
Answer : The correct option is, (a) 345 K
Explanation :
The conversion used for the temperature from degree Celsius to Kelvin is:
where,
= temperature in Kelvin
= temperature in centigrade
As we are given the temperature in degree Celsius is, 72
Now we have to determine the temperature in Kelvin.
Therefore, the temperature in Kelvin is, 345 K
