The theoretical yield of NaCl : 15 mol

<h3>Further explanation</h3>

Given

15 mol Na

15 mol Cl₂

Required

The theoretical yield of NaCl

Solution

Reaction

2Na + Cl₂ ⇒ 2NaCl

A theoretical yield is the amount of product that you calculate from the reaction equation according to the product and reactant coefficients

Find limiting reactant (mol : coefficient) :

Na = 15 : 2 = 7.5

Cl₂ = 15 : 1 = 15

The limiting reactant = Na(smaller ratio)

Mol of NaCl based on mol Na as limiting reactant.

From the equation, mol ratio of Na : NaCl = 2 : 2, so mol NaCl = <u>15 mol</u>

How many grams of KCI can be dissolved in 63.5. g of water at 80
Masteriza [31]

Answer:

35.8 g

Explanation:

Step 1: Given data

Mass of water: 63.5 g

Step 2: Calculate how many grams of KCl can be dissolved in 63.5. g of water at 80 °C

Solubility is the maximum amount of solute that can be dissolved in 100 g of solute at a specified temperature. The solubility of KCl at 80 °C is 56.3 g%g, that is, we can dissolve up to 56.3 g of KCl in 100 g of water.

63.5 g Water × 56.3 g KCl/100 g Water = 35.8 g KCl
