The molecular mass of magnesium in magnesium chloride is 24.305 grams/mol.
MgCO3 has a molar mass (molecular weight) of 84.3139 g/mol.
The molar mass of MgSO4.7H2O (magnesium sulfate heptahydrate) is calculated as the sum of the individual atomic masses of magnesium (Mg), sulfur (S), oxygen (O), and hydrogen (H). The molecular mass is approximately 246.47 g/mol.
Since the question is about molecular mass, the weight of the reactant copper (45.6 g) is not determining the answer.There are three possible copper nitrate products:Cu(I) nitrate, CuNO3 molecular mass is 125.5509 g.mol-1Anhydrous Cu(II) nitrate, Cu(NO3)2 : molecular mass is 187.5558 g.mol-1Cu(II) nitrate-trihydrate, (Cu(NO3)2).(3H2O) : molecular mass is 241.60 g/mol
Mass in grams = no of moles x molecular mass. So, mass in grams = 5.2x 56 = 291.2g
The molecular mass of magnesium in magnesium chloride is 24.305 grams/mol.
MgCO3 has a molar mass (molecular weight) of 84.3139 g/mol.
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.
148.3 g mol-1
The chemical formula of ammonium nitrite is NH4NO2; the molecular mass is 64,06 grams.
the formula is no. moles is mass / molecular mass. As the number of moles is 1, the mass required will be exactly the same as the molecular mass, which is 58.32g
The molar mass of MgSO4.7H2O (magnesium sulfate heptahydrate) is calculated as the sum of the individual atomic masses of magnesium (Mg), sulfur (S), oxygen (O), and hydrogen (H). The molecular mass is approximately 246.47 g/mol.

Mass in grams = no of moles x molecular mass. So, mass in grams = 5.2x 56 = 291.2g
To find the mass percentages of magnesium phosphate and water, you need to know their molecular weights. Then, calculate the total mass of the reactants by adding the masses of magnesium hydroxide and phosphoric acid. Compare this total mass to the sum of the masses of magnesium phosphate and water to find the mass percentages of each compound.
To calculate the percentage of magnesium by mass in a compound, divide the mass of magnesium by the total mass of the compound, then multiply by 100. Percentage of magnesium by mass = (mass of magnesium / total mass of compound) * 100.
