Molarity can be defined as the number of moles of solute in 1 L solution.
Molarity of Na₂SO₄ solution - 0.200 M
this means there are 0.200 moles in 1 L solution
Molar mass of Na₂SO₄ - 142 g/mol
therefore mass of Na₂SO₄ in 1.00 L - 0.200 mol x 142 g/mol = 28.4 g
a mass of 28.4 g of Na₂SO₄ is present in 1.00 L
<u>Answer:</u> 3 neutrons are produced in the above nuclear reaction.
<u>Explanation:</u>
In a nuclear reaction, the total mass and total atomic number remains the same.
The nuclear reaction for the fission of Americium-244 isotope follows:

<u>To calculate Y:</u>
Total mass on reactant side = total mass on product side

Hence, 3 neutrons are produced in the above nuclear reaction.
Answer:
This compound is Ammonium Sulphide and has molar mass 68 g/mol.
Explanation:
- Molar Mass : It is the mass of 1 mole of the substance and in grams.Its units are gram/mole.
- It is numerically equal to mass of the substance in atomic mass units
How to calculate Molar mass :
grams/mole
Molar mass of Ammonium sulphide is 68 g/mol
