Answer: 15
Explanation:
To find the atomic mass, you add the number of protons and neutrons. The number of electrons is the same as the number of protons
Mass of Magnesium nitrate produced : 593.2 g
<h3>Further explanation</h3>
The reaction equation is the chemical formula of reagents and product substances
A reaction coefficient is a number in the chemical formula of a substance involved in the reaction equation. The reaction coefficient is useful for equalizing reagents and products.
Reaction
2HNO₃ + Mg(OH)₂ → Mg(NO₃)₂ + 2H₂0
mol HNO₃ = 8
From the equation, mol ratio of HNO₃ : Mg(NO₃)₂ = 2 : 1, so mol Mg(NO₃)₂ :
Mass Mg(NO₃)₂(MW=148,3 g/mol) :

1.679 × 10²³ g of PbO₂ is present in 4.23×10⁴⁴ particles of PbO₂.
<u>Explanation:</u>
First the number of particles is converted into moles by dividing it by the Avogadro's number and then moles multiplied by the molar mass, we will get the mass of PbO₂ in grams.
4.23×10⁴⁴/ 6.022×10²³ = 7.02×10²⁰ moles
Now we have to multiply this by the molar mass of PbO₂, that is 239.2 g/mol, we will get the mass in grams.
7.02×10²⁰ moles × 239.2 g/mol = 1.679 × 10²³ g of PbO₂
Answer:
All the ionic compounds are simplest combination of the atoms. All the empirical formulas are the simplest way to write the chemical formulas. Thus, the ionic compound is usually in its empirical state.
Explanation:
Ionic compound are the chemical compound which are composed of the ions which are held together by the strong electrostatic forces which is termed as ionic bonding. The ionic compound is overall neutral, but it consists of positively charged ions which are known as cations and also negatively charged ions which are known as anions.
Since all the ionic compounds are simplest combination of the atoms and also, all the empirical formulas are simplest way to write the chemical formulas, the ionic compound is usually in its empirical state.
Thus it can be stated that:
All the ionic compounds are the empirical formulas, but not all the empirical formulas are the ionic compounds.
