Mg+2 NaF-> MgF2+2 Na
If you start with 5.5 grams of lithium chloride, how many grams of calcium chloride will be produced?
I think you have the wrong chemical equation. There is no lithium chloride or calcium chloride in your equation.
45.90
To determine the amount of calcium chloride produced, we need to calculate the theoretical yield using the given balanced chemical equation:
Mg + 2 NaF → MgF2 + 2 Na
The molar mass of MgF2 is 62.301 grams/mol.
Step 1: Calculate the molar mass of LiCl:
LiCl = 6.941 g/mol (molar mass of Li) + 35.453 g/mol (molar mass of Cl) = 42.394 g/mol
Step 2: Convert the given mass of LiCl to moles:
5.5 g LiCl * (1 mol LiCl / 42.394 g LiCl) = 0.1298 mol LiCl
Step 3: Use stoichiometry to find the moles of CaCl2 produced:
From the balanced equation, 1 mol Mg reacts with 1 mol MgF2.
Therefore, 0.1298 mol LiCl will react with (1 mol MgF2 / 2 mol NaF) * (2 mol LiCl / 1 mol Mg) = 0.0649 mol MgF2
Step 4: Convert the moles of MgF2 to grams:
0.0649 mol MgF2 * 62.301 g/mol (molar mass of MgF2) = 4.04 g MgF2
Thus, 4.04 grams of calcium chloride will be produced.
To determine how many grams of calcium chloride will be produced in the given reaction, we need to use the concept of stoichiometry. Stoichiometry is the relationship between the relative quantities of reactants and products in a chemical reaction.
First, let's write out the balanced chemical equation for the reaction:
Mg + 2 NaF -> MgF2 + 2 Na
From the balanced equation, we can see that the mole ratio between magnesium (Mg) and calcium chloride (CaCl2) is 1:1. This means that for every 1 mole of magnesium, 1 mole of calcium chloride will be formed.
To calculate the number of moles of magnesium using the given mass, we need to convert grams to moles. The molar mass of magnesium (Mg) is approximately 24.31 g/mol.
moles of magnesium = mass of magnesium / molar mass of magnesium
moles of magnesium = 5.5 g / 24.31 g/mol ≈ 0.23 mol
Using the mole ratio from the balanced equation, we know that the moles of calcium chloride produced will also be 0.23 mol.
Finally, to calculate the mass of calcium chloride, we need to convert moles to grams. The molar mass of calcium chloride (CaCl2) is approximately 110.98 g/mol.
mass of calcium chloride = moles of calcium chloride × molar mass of calcium chloride
mass of calcium chloride = 0.23 mol × 110.98 g/mol ≈ 25.51 g
Therefore, approximately 25.51 grams of calcium chloride will be produced when starting with 5.5 grams of lithium chloride.
