What is the mass of 4MgCl2?
To find the mass of 4 moles of magnesium chloride (MgCl2), you first need to calculate the molar mass of MgCl2. The molar mass is approximately 95.21 g/mol (24.31 g/mol for Mg and 35.45 g/mol for each Cl, with two Cl atoms). Thus, the mass of 4 moles of MgCl2 is calculated as 4 moles × 95.21 g/mol = 380.84 grams.
How much Mg and Cl is in MgCl2?
In one formula unit of MgCl2, there is one atom of magnesium (Mg) and two atoms of chlorine (Cl).
Balnced equation for Hydrochloric acid and magnesium?
Hydrochloric acid + magnesium ---> Magnesium chloride + hydrogen gasUnbalanced: HCl + Mg ---> MgCl2 + H2Balanced: 2HCl + Mg ---> MgCl2 + H2
Is SiCl plus Mg---MgCl2 plus Si Balanced?
The chemical equation SiCl + Mg → MgCl2 + Si is not balanced. To balance it, you would need to adjust the coefficients to ensure that the number of atoms of each element is the same on both sides of the equation.

Calculate the formula mass for MgCl2?
The formula mass for MgCl2 (magnesium chloride) is calculated by adding the atomic masses of magnesium (Mg) and chlorine (Cl). The atomic mass of Mg is 24.31 g/mol and the atomic mass of Cl is 35.45 g/mol. Multiplying the atomic mass of Cl by 2 (since there are 2 chlorine atoms in MgCl2) and adding it to the atomic mass of Mg gives a formula mass of 95.21 g/mol for MgCl2.
What is the ratio of Cl2 to Mg in MgCl2 if you have 0.03mol Mg and 0.06mol Cl2?
The balanced chemical equation for the reaction between Mg and Cl2 to form MgCl2 is: Mg + Cl2 -> MgCl2 From the equation, it can be seen that 1 mol of Mg reacts with 1 mol of Cl2 to produce 1 mol of MgCl2. Therefore, the ratio of Cl2 to Mg in MgCl2 would be 1:1.
What has the largest formula mass LiCl NaCl KCl MgCl2.?
MgCl2 has the largest formula mass among the given compounds. This is because the formula mass of a compound is the sum of the atomic masses of all the atoms in a formula unit, and magnesium (Mg) has a greater atomic mass than lithium (Li), sodium (Na), and potassium (K).
How many moles are there in 0.684g MgCl2?
To find the number of moles in 0.684g of MgCl2, you need to divide the mass by the molar mass of MgCl2. The molar mass of MgCl2 is 95.211 g/mol (24.305 g/mol for Mg and 35.453 g/mol for Cl). Dividing 0.684g by 95.211 g/mol gives approximately 0.0072 moles of MgCl2.
What is the mass of 9.40 moles of magnesium chloride MgCl2?
There is 9.40 mol of MgCl2 and you want to know how many grams (g). First find the atomic weight of the molecule. Mg = 24.312 Cl = 35.453 x 2 = 70.906 MgCl2 = 95.218 g/mol Then multiply the given moles by the atomic weight of the molecule to get the mass. 9.40 mol x 95.218 g/mol = 895.05 g MgCl2
