The molar mass of calcium (Ca) is approximately 40.08 g/mol. Therefore, 1 mole of calcium would weigh around 40.08 grams.
1 mole of neon weighs approximately 20.18 grams.
The atomic weight of copper is approximately 63.55 grams per mole. Therefore, 1 mole of copper weighs around 63.55 grams.
Use stoichometry to figure this out. 1 mole Fe * 56 g Fe ...............1 mole Fe
The mass of 1 mole of neutrons is approximately 1 gram. This is because the atomic mass unit (u) is defined based on the mass of a neutron, so one mole of neutrons would have a mass close to 1 gram.
1 mole of EDTA will chelate with 1 mole of Ca2+ ions or 1 mole of Fe2+ or Fe3+ ions.
1 mole of neon weighs approximately 20.18 grams.
It is 55.8 grams.
The atomic weight of copper is approximately 63.55 grams per mole. Therefore, 1 mole of copper weighs around 63.55 grams.
0.50 moles CaCO3 (1 mole Ca/1 mole CaCO3)(6.022 X 1023/1 mole Ca)= 3.0 X 1023 atoms of calcium===================
Use stoichometry to figure this out. 1 mole Fe * 56 g Fe ...............1 mole Fe
40 g of Ca = 1 mole So 808 g of Ca = 20.2 mole
First of all, we should know what a mole and molar mass of an element means. Then answering this question would be easy. Mole is a number( like pi, 1, 2, etc.). It is approximately 6.0225 *1023 . 1 mole of anything is same as the number of atoms in 12 grams of Carbon C12 sample. The mass of mole of an element/compound is called it's molar mass expressed in grams. The molar mass of a monoatomic element is equal to it's mass number. So, we know Ca's mass number = 40. that means 1 mole of Ca weighs 40 grams. =>1/40 mole of Ca weighs 1 gram. =>(1/40)*23 moles of Ca weighs 23.0 gram. =>0.575 moles of Ca weighs 23.0 gram. So there are 0.575 moles of Ca atoms in 23.0g of Ca
1 mole of O (oxygen) weighs 15. 9996 grams. By definition, 1 mole of any element is equal to its atomic weight expressed in grams. 1 mole is equal to 6.02 x 1023 atoms of that element.
To make 1 mole carbon dioxide it takes 2 moles of HCl and one mole of Ca-carbonate.
The mass of 1 mole of neutrons is approximately 1 gram. This is because the atomic mass unit (u) is defined based on the mass of a neutron, so one mole of neutrons would have a mass close to 1 gram.
This is a relatively simple question that can be answered using simple stochiometry. If we assume a few things: a) that pure elements are reacting, b) that oxygen is in its stable diatomic form, and c) that they are reacting on a 1 to 1 mole ratio; then the math is as follows: 1 g.O2 x (1 mole O2 / 32 grams per mole) x (1 mole Ca / 1 mole O2) x (40.078 grams per mole / 1 mole Ca) = XXX.XX grams of Ca Thus the amount of calcium that will react on a 1 to 1 mole ratio with one gram of diatomic oxygen (O2) is 1.252 grams of calcium
The mass of NH3 mole = its molecular weight = 14 + 3 x 1 = 17 The mass of H2O mole = its molecular weight = 2 x 1 + 16 = 18 This means that one mole of NH3 weigh less than one mole of H2O
