Answer:
4.5moles
Explanation:
Given parameters:
Mass of Na₃P = ?
Unknown:
Number of moles = ?
Solution;
The number of moles in a given substance can be derived from the expression below;
Number of moles = 
Molar mass of Na₃P = 3(23) + 31 = 100g/mol
Number of moles = 
= 4.5moles
The formula weight of CuCl is: 98.999
<span>Percent compositions are usually weight percent (abbreviated w/o). </span>
<span>Since CuCl has one mole of each element, the calculation is simple. </span>
<span>For Cu it is: (63.546 / 98.999) x 100% = 64.189 w/o </span>
<span>For Cl it is 100.000 - 64.189 = 35.811 w/o </span>
Answer:
Acetic acid is found in significant quantities in Vinegar
Aluminum sulfide : Al₂S₃
ratio cation : anion = 2 : 3
<h3>Further explanation</h3>
Given
Compound of Aluminium
Required
cations anions ratio
Solution
Salt can be formed from cations and anions which have their respective charges.
In the chemical compound formula these charges are crossed with each other
For aluminum it has a +3 charge
1. Aluminum carbide : Al₄C₃
ratio cation : anion = 4 : 3
2. Aluminum chloride : AlCl₃
ratio cation : anion = 1 : 3
3. Aluminum sulfide : Al₂S₃
ratio cation : anion = 2 : 3
4. Aluminum nitride : AlN
ratio cation : anion = 1 : 1
