Under STP condition, the gas has a rule of 22.4 L per mole. And according to the ideal gas law, V1/T1=V2/T2. Under STP, 1.5 mol gas has volume of 33.6 L. So the volume under 22 C is 33.6*295/273=36.3 L.
Answer:
B) mass
Explanation:
Triple beam balance -
It is an instrument , which is used for the measurement of the mass , in a very accurate and precise manner .
The error range of this balance is +/- 0.05 gram .
It consists of three beam , of three different sizes , where the difference in the beam shows the difference in the weights and readings .
Hence, from the given statement of the question,
The correct option is B. mass.
Acetylene appear as gas and is unstable and thus kept in presence of other solution such as liquid ammonia.
Ethanol on reacting with ammonia produces ethylamine as follows:
Ethanol again on reacting with ethylamine produces diethylamine and triethylamine as follows:

The energy of a photon whose frequency is 5.94 × 10¹⁷ Hz is 3.94 × 10-¹⁶J.
<h3>How to calculate energy?</h3>
The energy of a photon wave can be calculated by using the following formula:
E = hf
Where;
- E = energy (joules)
- h = Planck's constant (6.626 × 10-³⁴J/s)
- f = frequency
According to this question, a photon has a frequency of 5.94 x 10¹⁷ Hz. The energy can be calculated as follows:
E = 6.626 × 10-³⁴J/s × 5.94 x 10¹⁷ Hz
E = 3.94 × 10-¹⁶J
Therefore, 3.94 × 10-¹⁶J is the energy of the photon.
