How many moles in 200 grams of calcium?
There are 5 moles of calcium in 200 grams of calcium. This calculation is based on the molar mass of calcium, which is approximately 40 grams per mole.
How many grams of calcium in 418 grams of Ca CO 3?
There are 40.08 grams of calcium in 100 grams of CaCO3. To find the amount of calcium in 418 grams of CaCO3, you can set up a proportion and calculate that there are approximately 167.2 grams of calcium in 418 grams of CaCO3.
What is the formula of the compound iron III phosphide?
FeP. Iron(III) means that the iron has an oxidation state of 3, and could be considered to be Fe3+. Phosphides generally contain P3- and this is true for the group1 and group 2 metals There is one iron phosphide Fe3P used as a semiconductor, so it is not ionic! You cannot use oxidation number nomenclature on that compound you have to go the "triiron monophosphide" route instead. I do not think there is actually a compound with the formula FeP. Naming phosphides using the oxidation state nomenclature is risky, phosphorus forms many different "ions" and also forms binary compounds where the phosphorus is "interstitial" .
How do you write a formula when you have three times as many hydrogen atoms than phosphorus atoms?
The hydrogen phosphide (syn.: phosphine, phosphane) has the chemical formula PH3.
How many moles in 2.3 grams of phosphorus?
mole = mass/molar mass mass=2.3 grams molar mass=30.97 2.3/30.97=0.0742 moles
What is Ca3P3?
Ca3P3 is the chemical formula for calcium phosphide, a compound composed of calcium and phosphorus. It is often used as a pesticide and a rodenticide due to its toxic properties. Calcium phosphide reacts with water or moisture to produce phosphine gas, which is highly toxic to many organisms.
How many atoms of phosphorus does magnesium phosphide contain?
Magnesium phosphide (Mg3P2) contains 2 atoms of phosphorus.
How many atoms of of oxygen does hydrogen phosphide have?
None. Hydrogen phosphide, more commonly called phosphine, contains only hydrogen and phosphorus.
How many moles of calcium phosphide are in 444g?
The chemical formula for calcium phosphide is Ca3P2.Formula mass of Ca3P2 = 3(40.1)+2(31.0) = 182.3Amount of Ca3P2 = mass of sample / formula mass = 444/182.3 = 2.44mol

How many grams are in the 1.204 1020 atoms of phosphorus used to coat your television screen?
To calculate the grams of phosphorus, you need to know the molar mass of phosphorus and then use Avogadro's number to convert from atoms to grams. The molar mass of phosphorus is approximately 30.97 g/mol. Therefore, you can calculate the grams of phosphorus using this information.
