3 atoms of magnesium combine with 2 atoms of nitrogen.What will be the weight of magnesium which combines with 1.86g of nitrogen?
The molar mass of magnesium is 24.31 g/mol and the molar mass of nitrogen is 14.01 g/mol. So, 1.86g of nitrogen is equivalent to 0.133 mol. From the 3:2 ratio of magnesium to nitrogen, we find that 0.133 mol of nitrogen requires 0.1995 mol of magnesium. Therefore, the weight of magnesium combining with 1.86g of nitrogen is 4.85g.
Mass of 3.65 mol Mg?
To solve this first the molar mass of Mg is needed (look at a periodic table). (Mg=23.0g/mol) Then convert the mols to grams as follows: (3.65 mol Mg) x (23.0 g/mol Mg) = 84.0 g Mg The mol units cancel in the conversion leaving only the gram units and the ammount in grams.
What is the molar mass of mg o?
The molar mass of magnesium oxide (MgO) is approximately 40.3 g/mol.
What is the molar mass of MgS?
The molar mass of MgS (magnesium sulfide) is calculated by adding the atomic masses of magnesium (Mg) and sulfur (S). The atomic mass of Mg is approximately 24.31 g/mol, and S is approximately 32.06 g/mol. Therefore, the molar mass of MgS is approximately 24.31 + 32.06 = 56.37 g/mol.
What is the formula mass of magnesium nitrite octahydrate?
The formula mass of magnesium nitrite octahydrate (Mg(NO2)2 * 8H2O) can be calculated by adding the atomic masses of all the elements in the compound. The atomic mass of Mg is 24.3 g/mol, N is 14.0 g/mol, O is 16.0 g/mol, and H is 1.0 g/mol. By adding these up, you get the formula mass of magnesium nitrite octahydrate.

The molar mass of MgH2 is calculated by adding the atomic masses of magnesium (Mg) and hydrogen (H). The atomic mass of Mg is approximately 24.31 g/mol, and the atomic mass of H is approximately 1.008 g/mol. Therefore, the molar mass of MgH2 is approximately 25.33 g/mol.
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 percent composition by mass of chlorine in Mg(CLO4)2?
To find the percent composition of an element, you need to calculate the molar mass of the element in the compound and divide it by the molar mass of the whole compound, then multiply by 100. The molar mass of Mg(ClO4)2 is approximately 223.21 g/mol. The molar mass of chlorine in the compound is 70.906 g/mol. Therefore, the percent composition of chlorine in Mg(ClO4)2 is (70.906 g/mol / 223.21 g/mol) x 100 = 31.74%.
What is the formula mass of Mg(NO3)2?
The formula mass of Mg(NO3)2, also known as magnesium nitrate, is 148.32 g/mol. This is calculated by adding the atomic masses of magnesium (24.31 g/mol), nitrogen (14.01 g/mol), and three oxygen atoms (16.00 g/mol each) together.
