Answer: The percentage composition of hydrogen in the given compound is 15%.
Explanation:
To calculate the percentage composition of hydrogen in a compound, we use the formula:
Where,
Mass of hydrogen = 41.4 grams
Mass of compound = 276 grams
Putting values in above equation, we get:
Percentage composition of hydrogen in a given compound = 15%
Answer:
Explanation:
Given that:
Mass of , m = 45.0 g
Molar mass of , M = 30.01 g/mol
Temperature = 20.0 °C
The conversion of T( °C) to T(K) is shown below:
T(K) = T( °C) + 273.15
So,
T₁ = (20.0 + 273.15) K = 293.15 K
V = ?
Pressure = 740 mm Hg
Considering,
Using ideal gas equation as:
where,
P is the pressure
V is the volume
m is the mass of the gas
M is the molar mass of the gas
T is the temperature
R is Gas constant having value = 62.36367 L. mmHg/K. mol
Applying the values in the above equation as:-
