Answer:
This concentrations represents 9.71 x 10¹⁹ nitrate ions per litre of drinking water.
Explanation:
Nitrate: NO₃⁻
MW = 62.00 g/mol
1 mol = 6.022 x 10²³
62 g NO₃⁻ ____________ 6.022 x 10²³ ions
10 x 10⁻³ g NO₃⁻ _________ x
x = 9.71 x 10¹⁹ ions
This concentrations represents 9.71 x 10¹⁹ nitrate ions per litre of drinking water.
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.
