how many grams of Mg combine with 1.50 g of Cl ions in MgCl2 ?

Convert 1.50 g Cl ions to moles.

moles = grams/atomic mass = ??
moles Mg = moles Cl x 1/2 = ??
g Mg = moles Mg x atomic mass Mg.

balance the equation. Figure the moles of Cl2

Then, how many moles do you need to react with that number of moles of Cl2

Why did the chemist break up with magnesium? Because it kept stealing electrons! Okay, let's calculate the grams of Mg that combine with 1.50 g of Cl ions in MgCl2.

The atomic mass of Mg is 24.31 g/mol, and since there's a 1:2 ratio of magnesium to chloride in MgCl2, we can calculate the grams of magnesium that combine with 1.50 g of Cl ions.

First, let's calculate how many moles of Cl ions we have:
Moles of Cl = mass / molar mass = 1.50 g / (35.45 g/mol) = 0.0423 mol

Now, since the ratio is 1:2, we will have twice the number of moles of magnesium:
Moles of Mg = 2 * moles of Cl = 2 * 0.0423 mol = 0.0846 mol

Lastly, let's convert moles of Mg to grams:
Grams of Mg = moles * molar mass = 0.0846 mol * (24.31 g/mol) = 2.06 g

So, approximately 2.06 grams of Mg combine with 1.50 g of Cl ions in MgCl2.

To determine how many grams of Mg combine with 1.50 g of Cl ions in MgCl2, we need to understand the mole ratio between Mg and Cl in the compound.

The chemical formula of magnesium chloride (MgCl2) tells us that for every 1 mole of MgCl2, there are 1 mole of Mg atoms and 2 moles of Cl ions.

We can start by calculating the number of moles of Cl ions in 1.50 g of Cl ions using the molar mass of Cl.

The molar mass of Cl is 35.45 g/mol.

Number of moles of Cl ions = mass of Cl ions / molar mass of Cl
Number of moles of Cl ions = 1.50 g / 35.45 g/mol

Calculating this:

Number of moles of Cl ions = 0.0423 moles

Now that we know the number of moles of Cl ions, we can determine the number of moles of Mg required to react with them.

Since the mole ratio of Mg to Cl in MgCl2 is 1:2, we can infer that the number of moles of Mg is half of the number of moles of Cl ions.

Number of moles of Mg = 0.0423 moles / 2
Number of moles of Mg = 0.0212 moles

Finally, we can calculate the mass of Mg using the number of moles and the molar mass of Mg.

The molar mass of Mg is 24.31 g/mol.

Mass of Mg = number of moles of Mg x molar mass of Mg
Mass of Mg = 0.0212 moles x 24.31 g/mol

Calculating this:

Mass of Mg = 0.514 g

Therefore, approximately 0.514 grams of Mg combine with 1.50 g of Cl ions in MgCl2.

To find out how many grams of Mg combine with 1.50 g of Cl ions in MgCl2, we need to understand the molecular formula of MgCl2 and the molar masses of Mg and Cl.

The molecular formula of MgCl2 tells us that one molecule of MgCl2 contains one Mg atom and two Cl ions. Therefore, we can break down the problem into two steps:

Step 1: Calculate the molar mass of Mg.
The molar mass of an element or compound is the mass of one mole of that substance. The molar mass of Mg is 24.31 g/mol. This value can be found using the periodic table.

Step 2: Calculate the number of moles of Cl ions in 1.50 g.
To find the number of moles, we divide the mass of Cl ions by their molar mass. The molar mass of Cl is 35.45 g/mol.

Number of moles of Cl ions = Mass of Cl ions (in grams) / Molar mass of Cl

Number of moles of Cl ions = 1.50 g / 35.45 g/mol

Now, we have the number of moles of Cl ions. Since the ratio in the formula MgCl2 is 1:2 (one Mg atom for every two Cl ions), this means we need twice the number of moles of Mg as the number of moles of Cl ions.

Number of moles of Mg = 2 * Number of moles of Cl ions

Finally, to find the mass of Mg, we multiply the number of moles of Mg by its molar mass.

Mass of Mg = Number of moles of Mg * Molar mass of Mg

Therefore, using the obtained values, you can find the mass of Mg that combines with 1.50 g of Cl ions in MgCl2.
