Answer:
4) 0.5507 Mol Ar
5) 44.548 Mol AgNO3
6) 2.16107 Mol Li
Explanation:
Divide = grams to mol and mol to molecules
Multiply = molecules to mol and mol to grams.
3) 22 <em>g of Ar</em> 1 mol 22
-------------------- * ---------------------- = ------------ (turn to decimal) = 0.5507 Mol Ar
39.948 <em>g of Ar</em> 39.948
4) AgNO3 = (Ag; 39.948) (N; 14.007) (O^3; 48)
39.948 + 14.007 + 48 = 101.955
7.4 x 10^23 Mc 6.02 x 10^23 Mc
---------------------- * ------------------------- = 44.548 Mol AgNO3
1 mol
5)
15g 1 Mol 15
------- * ------------------- = --------- (turn to decimal) = 2.16107 Mol Li
6.941 g of Li 6.941
Cesium Sulfite is formed from the Cs cation and the SO₃⁻² anion. The correct formula for this compound is Cs₂SO₃.
<h3>What is Cation ? </h3>
Cations are positively charged ions. It forms when an element lose one or more electrons.
<h3>
What is Anion ? </h3>
Anions are negatively charged ions. It form when an element gains one or more electrons.
Symbol Cs⁺¹ SO₃⁻²
Valency +1 -2
Formula of the compound is Cs₂SO₃.
Thus from the above conclusion we can say that Cesium Sulfite is formed from the Cs cation and the SO₃⁻² anion. The correct formula for this compound is Cs₂SO₃.

Answer:
To keep the evinermental machinces working
Explanation:
Ca(OH)₂ = Ca²⁺ + 2OH⁻
[OH⁻]=2c{Ca(OH)₂}
pH=14+lg[OH⁻]
pH=14+lg(2c{Ca(OH)₂})
pH=14+lg(2*0.0075)=12.18
