Explanation:
The answer is shape.
Basically, quantities can either be fundamental or derived. While fundamental are the basic quantities, derived are obtained from combining fundamentals.
To get a shape, we would need the combination of lengths. This makes the shape a derived quantity
Answer: 3.61 L
Explanation:
To calculate the moles, we use the equation:
2 moles of produce = 3 moles of
0.1 moles of produce = moles of
According to the ideal gas equation:'
P = Pressure of the gas = 1 atm (NTP)
V= Volume of the gas = ?
T= Temperature of the gas = 20°C = (20+273) K = 293 K (NTP)
R= Value of gas constant in in kilopascals = 0.0821 Latm/K mol
Thus volume of oxygen at NTP obtained by decomposing 12.26 g of is 3.61 L
