24.31 g per mole
MgCO3 has a molar mass (molecular weight) of 84.3139 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 cytosine is 111,10.
The chemical formula of ammonium nitrite is NH4NO2; the molecular mass is 64,06 grams.

148.3 g mol-1
MgCO3 has a molar mass (molecular weight) of 84.3139 g/mol.
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

Magnesium chloride, MgCl2, has a molecular mass of has a molar mass of 95.21 g/mol. So, 53.8 g MgCl / 95.21 g/mol is 0.565 mol MgCl2.
Tin (ii) Nitrite also called Stannous Nitrite, has the formula Sn(NO2)2 and a molar mass of 210.721
First find the formula, which is Mg(NO3)2. Next, find the masses of each element and add them up. These numbers are found to the right of the atomic number on the periodic table of elements. Mg is 24.3g. N is 14g, but since there are two NO3s it will be 28g. Then you have 6 O each with a mass of 16g, equalling 48g. now add 24.3g + 28g + 96g to find the formula weight, which is 148.3g.
