Moles of PF₃ : 4
<h3>Further explanation</h3>
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
1.25 moles of P₄(s) is reacted with 6 moles of F₂(g)
Limiting reactant : the smallest ratio (mol divide by coefficient)
P₄ : F₂ =
mol PF₃ based on mol of limiting reactant(F₂), so mol PF₃ :
Molarity is the ratio of the moles and the volume. The mass of 2.6 M sodium phosphate solution is 2131.22 gms.
<h3>What is mass?</h3>
Mass is the product of the moles and the molar mass of the substance. It is given as,
Mass = Moles × Molar mass
The moles from molar concentration is used to calculate mass as:
Mass = Molarity × volume × molar mass
= 2.6 × 5.0 × 163.94
= 2131.22 gms
Therefore, 2131.22 gms is the mass of sodium phosphate.
