A. Mass of the unknown gas.
The mass of the unknown gas is calculated by subtracting the weight of the empty flask from the mass when there was air in it.
m = 126.593 g - 125.623 g
Simplifying,
m = 0.97 grams
b. Molar mass of the gas
The molar mass of the gas is calculated by the ideal gas law.
PV = (m/M)RT
where P is pressure,V is volume, m is the mass, M is the molar mass, R is the universal gas constant, and T is temperature. Substituting the known values to the equation,
(733 mmHg/760 mmHg/atm)(0.20 L) = (0.97 g/M)(0.0821 L.atm/molK)(99 + 273.15 K)
The value of M in the equation is 153.64 g/mol.
<em>Answer: 153.64 g/mol</em>
Answer:
Volume of AgNO₃ = 4.9 ml (Approx)
Explanation:
Given:
Total solution = 75 ml
Volume of AgNO₃ = 6.5%
Find:
Volume of AgNO₃
Computation:
Volume of AgNO₃ = Total solution x Volume of AgNO₃
Volume of AgNO₃ = 75 x 6.5%
Volume of AgNO₃ = 4.875
Volume of AgNO₃ = 4.9 ml (Approx)
