What is the mass, in grams, of 0.00948\,\text {mol}0.00948mol0, point, 00948, start text, m, o, l, end text of phosphoric acid?
ANEK [815]
Answer:
0.929g
Explanation:
The following were obtained from the question.
Number of mole of phosphoric acid (H3PO4) = 0.00948mol.
Mass of H3PO4 =?
The mass in grams of phosphoric acid (H3PO4) can be obtained as follow:
Number of mole of H3PO4 = 0.00948mol.
Molar Mass of H3PO4 = (3x1) + 31 + (16x4) = 3 + 31 + 64 = 98g/mol
Mass of H3PO4 =?
Mass = number of mole x molar Mass
Mass of H3PO4 = 0.00948 x 98
Mass of H3PO4 = 0.929g
Answer: The final temperature of the gas is 7.58 °C.
Explanation: We are given initial and final pressure of the system and we need to find the final temperature of the system.
To calculate it, we use the equation given by Gay-Lussac.
His law states that pressure is directly related to the temperature of the gas.
Or,
where,
= initial pressure = 893 mmHg = 1.175atm (Conversion factor: 1atm = 760mmHg)
= initial temperature = 49.3°C = [49.3 + 273.15]K = 322.45K
= Final pressure = 778mmHg = 1.023atm
= Final temperature = ?°C
Putting values in above equation, we get:
Converting Final temperature from kelvin to degree Celsius.
Hence, the final temperature of the gas is 7.58 °C.
