If an antacid weighs 2.50g and contains 400mg magnesium hydroxide what is the percentage of the tablet that is magnesium hydroxide?
The weight of the tablet is 2.50g, which is the total weight. The weight of magnesium hydroxide is 400mg. To find the percentage, convert the weight of magnesium hydroxide to grams (0.400g) and divide by the total weight, then multiply by 100. The percentage of the tablet that is magnesium hydroxide is 16%.
HOW TO GET percent of magnesium by mass?
To calculate the percentage of magnesium by mass in a compound, divide the mass of magnesium by the total mass of the compound, then multiply by 100. Percentage of magnesium by mass = (mass of magnesium / total mass of compound) * 100.
What is the mass percentage of magnesium in milk of magnesia?
Milk of magnesia is a suspension of magnesium hydroxide in water. The mass percentage of magnesium in milk of magnesia can vary but typically ranges from around 7-8%.
What is the percentage of elemental magnesium in magnesium stearate?
Magnesium stearate is composed of approximately 6-8% magnesium. The rest of the compound is made up of stearic acid, which accounts for the remaining 92-94% of the substance.
What percent of atoms of magnesium have a mass if exactly 24amu?
Magnesium has three stable isotopes: magnesium-24 (with an atomic mass of about 24 amu), magnesium-25, and magnesium-26. Approximately 79% of naturally occurring magnesium consists of magnesium-24, meaning that about 79% of magnesium atoms have a mass of exactly 24 amu. The remaining percentage is made up of the other isotopes.
What is the percentage of sulfur in magnesium sulfate?
The percentage of sulfur in magnesium sulfate is 32.2%.
What one has a higher mass percent of magnesium MgO or Mg3N2?
Magnesium nitride (Mg3N2) has a higher percentage composition of magnesium than magnesium oxide (MgO) does. The percentage composition of magnesium in magnesium nitride is 72.2% and the percentage composition of magnesium in magnesium oxide is 60.3%.

What is the percent composition of magnesium (mg) on MgO?
60%
Would the percent of oxygen be more or less if magnesium was heated twice but not at a constant weight?
If magnesium is heated twice but not at a constant weight, the percent of oxygen in the reaction could vary depending on the amount of magnesium present during each heating. When magnesium burns, it reacts with oxygen to form magnesium oxide, consuming oxygen in the process. If the magnesium weight decreases during the second heating, it could lead to a lower percentage of oxygen in the final product, as there would be less magnesium to react with the available oxygen. Conversely, if more magnesium is added for the second heating, the oxygen percentage would increase accordingly.
When 2.4 g of magnesium burns in excess oxygen 3.6 g of magnesium oxide is formed What is the percentage yield?
To calculate the percentage yield, we first need to determine the theoretical yield of magnesium oxide (MgO) from the given amount of magnesium. The molar mass of magnesium is approximately 24.3 g/mol, and that of magnesium oxide is about 40.3 g/mol. The balanced reaction shows that 2 moles of Mg produce 2 moles of MgO, meaning 2.4 g of Mg should theoretically yield about 3.6 g of MgO. Since the actual yield is also 3.6 g, the percentage yield is calculated as (actual yield/theoretical yield) × 100%, which results in a percentage yield of 100%.
What is the percentage of Mg-26 found in nature?
Natural magnesium is mainly composed of three stable isotopes: Mg-24, Mg-25, and Mg-26. The percentage of Mg-26 in natural magnesium is approximately 11.14%.
