[2][3], As a hydrate, it is useful as a corrosion inhibitor and pigment,[4] or as an ingredient in cosmetics. The reason is that the molar mass of the substance affects the conversion. Linear Formula: MgCrO 4: MDL Number: N/A: EC No. Magnesium was discovered by Joseph Black in 1775 and first isolated by Sir Humphrey Davy in 1808. First week only $4.99! Magnesium Chromate MgCrO4 bulk & research qty manufacturer. Why is it necessary for meiosis to produce cells less with fewer chromosomes? What is the name of the compound with the formula NaCH3COO? close. This quantity is called the formula mass. 0000086800 00000 n Formula weights are especially useful in determining the relative weights of reagents and products in a chemical reaction. Example Reactions: Mg(NO3)2 + Na2CrO4 = 2 NaNO3 + MgCrO4 SnCl2 + MgCrO4 = SnCrO4 + MgCl2 0000084698 00000 n a. iron (III) phosphate, FePO4 b. magnesium dichromate, MgCrO4 c. lithium carbonate, LiCO3 d. ammonium sulfite, (NH4)2S a. iron (III) phosphate, FePO4 Which of the following compounds contains the lead (II) ion? For bulk stoichiometric calculations, we are usually determining molar mass, which may also be called standard atomic weight or average atomic mass. The percent by mass of magnesium in MgCrO4 3. Magnesium chromate is a chemical compound, with the formula MgCrO4. Thus, for Ca(NO3)2, the subscript 2 implies two complete nitrate ions, so we must sum the masses of two (1 2) nitrogen atoms and six (3 2) oxygen atoms, along with the mass of a single calcium atom: The key to calculating the formula mass of an ionic compound is to correctly count each atom in the formula and multiply the atomic masses of its atoms accordingly. 0000000916 00000 n Thus, we set up the sum as follows: Formula masses of ionic compounds can be determined from the masses of the atoms in their formulas.
