What is the empirical formula of a compound that is 40 sulfur and 60 oxygen by weight?

The empirical formula for a compound with 40% sulfur and 60% oxygen by weight would be SO3 (sulfur trioxide). This is because the ratio of sulfur to oxygen is 1:3 in this compound.


How much does 40 worth of cocaine weigh in grams?

The weight of cocaine can vary depending on its purity and form. On average, a gram of cocaine is typically sold for around $40. Therefore, if you were to purchase $40 worth of cocaine, you would likely be getting around 1 gram of the substance.


What is sodium content of salt?

Salt is about 40% sodium by weight. For example, in a 1 gram portion of table salt, there is about 0.4 grams of sodium.


How many grams of iron will be needed to react completely with an excess of oxygen to form 40 grams of iron3 oxide?

To determine the amount of iron needed to react with 40 grams of iron(III) oxide, you should use the stoichiometry of the reaction. Calculate the molar mass of iron(III) oxide (Fe2O3) and determine the molar ratio between iron and iron(III) oxide in the balanced chemical equation. From there, you can calculate the amount of iron needed to fully react with 40 grams of iron(III) oxide.

What is the gram molecular weight of Sodium hydroxide if its molecular mass is 40 a.m.u?

The a.m.u. is defined as the fraction of 1/12 of an atom of the carbon-12 isotope. The value is pretty nearer to the mass of a hydrogen atom. Therefore, in every compound, the gram molecular weight is numerically equal to the molecular mass in atomic mass units. Therefore the gram molecular weight of NaOH is 40 g/mol.
