The molecular mass of sodium nitrate is 84,9947.
Molecular mass of sulfuric acid is 98 u. Molecular mass of potassium and nitrate ions are 39 and 62 respectively. The molar mass of potassium nitrate is 101u.
The molecular mass of magnesium in magnesium chloride is 24.305 grams/mol.
First, determine the molar mass of magnesium nitrate (Mg(NO3)2) by adding the atomic masses of magnesium, nitrogen, and oxygen. Then, divide the given mass (9.00g) by the molar mass to find the moles of magnesium nitrate.
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
To find the number of moles in 13.5 grams of magnesium nitrate, you need to divide the given mass by the molar mass of magnesium nitrate. The molar mass of magnesium nitrate (Mg(NO3)2) is 148.31 g/mol. Moles of magnesium nitrate = 13.5 grams / 148.31 g/mol ≈ 0.091 moles
Dissolve magnesium mass with nitric acid, then evaporate/boil the liquid away
MgCO3 has a molar mass (molecular weight) of 84.3139 g/mol.
Yes, magnesium reacts with copper nitrate to form magnesium nitrate and copper. The reaction involves the displacement of copper from the copper nitrate solution by magnesium.
Mg(NO3)2 is called magnesium nitrate. You do not use the prefix di for the nitrate since this is an ionic compound, and it can only be (NO3)2 as nitrate has a -1 charge and Mg has a +2 charge.
You don't: Magnesium nitrate is already neutral!
