## calculate the percent composition of magnesium chlorate

Kisamaria. What mass of ammonium chlorate is needed to decompose to give off 200 liters of oxygen? Answer Save. questions: C = 12, Cl = 35.5, Fe = 56, H = 1, Mg = 24, N = 14, Na = 23, O = 16, S = 32, By now I assume you can do formula mass calculations and read formula without any trouble, so ALL the detail of such calculations is NOT shown, just the bare essentials! Molar mass calculator also displays common compound name, Hill formula, elemental composition, mass percent composition, atomic percent compositions and allows to convert from weight to number of moles and vice versa. Ascorbic acid (vitamin C) contains 40.92% carbon, 4.58% hydrogen, and 54.50% oxygen by mass. In chemistry, the formula weight is a quantity computed by multiplying the atomic weight (in atomic mass units) of each element in a chemical formula by the number of atoms of that element present in the formula, then adding all … 9 years ago. Magnesium reacts vigorously when heated in the presence of air. Mg(ClO3)2 turns into MgCl2 + O2. Percent composition in chemistry typically refers to the percent each element is of the compound's total mass.. Your car burns mostly octane, C 8 H 18, as a fuel. How much (grams) magnesium hydroxide do you need to use in the above reaction to produce 500 liters of ammonia? Percent Composition Calculator. Relevance. How much strontium bromide is needed to add to chlorine gas to produce 75 liters of bromine? The basic equation = mass of element / mass of compound X 100%. Although there is a higher percentage of N 2 gas in the atmosphere than O 2, O 2 is more reactive and the magnesium oxide forms in a greater amount than the nitride. Computing molecular weight (molecular mass) I was just wondering if some body could balance the equation- the formula is . The percent composition is used to describe the percentage of each element in a compound. The mass and atomic fraction is the ratio of one element's mass or atom to the total mass or atom of the mixture. The percent composition can be found by dividing the mass of each component by total mass. Can you balance the equation- Magnesium Chlorate is decomposed by heating into magnesium chloride and oxygen? The Mg-O 2 reaction is energetic enough to allow some Mg to react with gaseous N 2. Assume a 100-g sample of ascorbic acid. What is the percentage by mass of chlorine in magnesium chlorate, Mg(ClO3)2? 3 Answers. Other percentage mass composition calculations including % of any component in a compound or a mixture. The Merck Index is the definitive reference work for scientists and professionals looking for authoritative information on chemicals, drugs and biologicals. For instance, if you had a 80.0 g sample of a compound that was 20.0 g element X and 60.0 g element y then the percent composition of each element would be: Molar Mass: 159.2086 4b. Thanks and have a good day! Atomic masses used for 4b. Magnesium Chlorite Mg(ClO2)2 Molar Mass, Molecular Weight. ››More information on molar mass and molecular weight.
