Formulas of Salts in Increasing Order of Relative Molecular Mass

The formulas of the salts in increasing order of relative molecular mass are as follows:

1. MnF2 (Manganese(II) fluoride) 2. Sn(NO3)2 (Tin(II) nitrate) 3. Li2SiO3 (Lithium silicate) 4. CuSO4 (Copper(II) sulfate)

Please note that the relative molecular mass of a compound is the sum of the atomic masses of all the atoms in its formula. The order of the salts provided above is based on their increasing relative molecular mass.

Let's discuss each salt in more detail:

1. MnF2 (Manganese(II) fluoride): - Manganese(II) fluoride is an inorganic compound with the formula MnF2. - It consists of one manganese atom (Mn) and two fluoride atoms (F). - The relative molecular mass of MnF2 can be calculated by adding the atomic masses of manganese and fluorine. - The atomic mass of manganese (Mn) is approximately 54.94 g/mol, and the atomic mass of fluorine (F) is approximately 18.99 g/mol. - Therefore, the relative molecular mass of MnF2 is approximately 54.94 + (2 * 18.99) = 92.92 g/mol.

2. Sn(NO3)2 (Tin(II) nitrate): - Tin(II) nitrate is an inorganic compound with the formula Sn(NO3)2. - It consists of one tin atom (Sn) and two nitrate ions (NO3-). - The relative molecular mass of Sn(NO3)2 can be calculated by adding the atomic masses of tin, nitrogen, and oxygen. - The atomic mass of tin (Sn) is approximately 118.71 g/mol, the atomic mass of nitrogen (N) is approximately 14.01 g/mol, and the atomic mass of oxygen (O) is approximately 16.00 g/mol. - Therefore, the relative molecular mass of Sn(NO3)2 is approximately 118.71 + (2 * (14.01 + (3 * 16.00))) = 246.72 g/mol.

3. Li2SiO3 (Lithium silicate): - Lithium silicate is an inorganic compound with the formula Li2SiO3. - It consists of two lithium atoms (Li), one silicon atom (Si), and three oxygen atoms (O). - The relative molecular mass of Li2SiO3 can be calculated by adding the atomic masses of lithium, silicon, and oxygen. - The atomic mass of lithium (Li) is approximately 6.94 g/mol, the atomic mass of silicon (Si) is approximately 28.09 g/mol, and the atomic mass of oxygen (O) is approximately 16.00 g/mol. - Therefore, the relative molecular mass of Li2SiO3 is approximately (2 * 6.94) + 28.09 + (3 * 16.00) = 109.91 g/mol.

4. CuSO4 (Copper(II) sulfate): - Copper(II) sulfate is an inorganic compound with the formula CuSO4. - It consists of one copper atom (Cu), one sulfur atom (S), and four oxygen atoms (O). - The relative molecular mass of CuSO4 can be calculated by adding the atomic masses of copper, sulfur, and oxygen. - The atomic mass of copper (Cu) is approximately 63.55 g/mol, the atomic mass of sulfur (S) is approximately 32.07 g/mol, and the atomic mass of oxygen (O) is approximately 16.00 g/mol. - Therefore, the relative molecular mass of CuSO4 is approximately 63.55 + 32.07 + (4 * 16.00) = 159.61 g/mol.

Please note that the values provided for the relative molecular masses are approximate and may vary slightly depending on the isotopic composition of the elements involved.
