How many atoms are in 3 moles of nitrogen
olga nikolaevna [1]

Answer:1 mol of Mg(NO3)2 contains 6.022*10^23 molecules

3 mol Mg(NO3)2 contains 3*6.022*10^23 = 1.81*10^24 molecules

Each Mg(NO3)2 molecule contains 2 N atoms  

Number of N atoms = 2*1.81*10^24 = 3.62*10^24 N atoms.

The red arrow is pointed at different locations of an atom of Helium. Where is it pointing to the GREATEST concentration of atom
Mama L [17]

Answer:

A is the correct answer.

Explanation:

An atom consist of electron, protons and neutrons. Protons and neutrons are present with in nucleus while the electrons are present out side the nucleus.

All these three subatomic particles construct an atom. A neutral atom have equal number of proton and electron. In other words we can say that negative and positive charges are equal in magnitude and cancel the each other. For example if neutral atom has 6 protons than it must have 6 electrons. The sum of neutrons and protons is the mass number of an atom while the number of protons are number of electrons is the atomic number of an atom.

For example  in case of Helium:

The 1st one diagram shows that arrow is pointing with in nucleus. The helium nucleus contain two protons and two neutrons. Thus maximum mass is present with in nucleus. while two electrons are revolve around the nucleus and mass of electron is negligible.

JulsSmile [24]

Answer:

2.1

Explanation:

Calculation of moles of Ba(OH)_2.8H_2O

Mass of copper = 5.3 g

Molar mass of copper = 315.46 g/mol

The formula for the calculation of moles is shown below:

moles = \frac{Mass\ taken}{Molar\ mass}

Thus,

Moles= \frac{5.3\ g}{315.46\ g/mol}

Moles of Ba(OH)_2.8H_2O = 0.0168 moles

According to the reaction,

Ba(OH)_2.8H_2O + H_2C_2O_4.2H_2O\rightarrow BaC_2O_4 + 12 H_2O

1 mole of Ba(OH)_2.8H_2O react with 1 mole of  H_2C_2O_4.2H_2O

0.0168 moles of Ba(OH)_2.8H_2O react with 0.0168 moles of  H_2C_2O_4.2H_2O

Moles of H_2C_2O_4.2H_2O = 0.0168 moles

Molar mass of H_2C_2O_4.2H_2O = 126.07 g/mol

Thus,

<u>Mass = Moles * Molar mass = 0.0168 moles * 126.07 g/mol = 2.1 g</u>

<u>Answer - 2.1</u>
