i dont really know how to explain but its the math
Explanation:
296.8249919999934
The mass of 2.28 mol of SO₃ is 182.4 g.
<h3>What is mass?</h3>
Mass can be defined as the quantity of matter a body contains.
The S.I unit of mass is kilogram (kg). other units of mass include grams (g), milligram (mg), microgram (μg) etc.
<h3>What is a matter?</h3>
A matter is anything that has mass and occupies space. Matter exist in three states.
- Solid state
- Liquid state
- Gaseous state
To calculate the mass of 2.28 mol of SO₃, we use the formula below.
Formula:
- m = nM............. Equation 1
⇒ Where:
- m = mass of SO₃
- n = number of mole of SO₃
- M = molar mass of SO₃
From the question,
Given:
Substitute these values into equation 1
Hence, the mass of 2.28 mol of SO₃ is 182.4 g.

Answer:
3.4x10⁻¹⁹J is the energy of the photon
Explanation:
To find the energy of a photon from its frequency we must use the equation:
E = hf
<em>Where E is the energy of the photon in J, our incognite</em>
<em>h is Planck's constant = 6.6262x10⁻³⁴Js</em>
<em>And f is the frequency = 5.2x10¹⁴Hz = 5.2x10¹⁴s⁻¹</em>
<em />
Replacing:
E = 6.6262x10⁻³⁴Js*5.2x10¹⁴s⁻¹
E = 3.4x10⁻¹⁹J is the energy of the photon
