How many grams of chlorine are required to combine with 24.4grams of silicon to form silicon tetrachloride?
Si + 2Cl2 --> SiCl4 24.4 grams silicon (1 mole Si/28.09 grams)(2 mole Cl2/1 mole Si)(70.9 grams/1 mole Cl2) = 123 grams chlorine needed =====================
If 32 grams of an element was equal to 1 mole of the element what is that element?
There are 32 grams of sulfur in a mole of that element. There are also 32 grams of oxygen in one mole of oxygen as it is found in its natural state (O2).
An iron chloride compound contains 55.85 grams of iron and 106.5 grams of chlorine What is the most likely empirical formula for this compound?
Fe3Cl
How many MOLES of sodium nitrate are present in 2.85 grams of this compound?
How many MOLES of sodium nitrate are present in 2.85 grams of this compound ?
Is 15 grams of oxygen gas and 22 grams of nitrogen gas a mixture or a compound?
Mixture
According to Dalton if 2 grams of element X combine with 4 grams of element Y to form compound XY how many grams of element X would combine with 28 grams of element Y to form the same compound?
This is just simple maths. If you need 2 grams of X for every 4 grams of Y, you need to multiply this up to the scale you are given 2x = 4y 4x = 8y 6x = 12y So you would need 6 grams of element X to make the same compound.

banana element
How do you calculate the grams of an element in a specific amount of a compound?
Multiply the mass of the compound by the conversion factor based on the percent composition of the element in the compound
How many grams of o2 are needed to combine with 6.85g of P?
8.85
How many grams are needed to have 5.00 moles?
This depends on the compound.
A compound is formed when 48 grams of carbon 8 grams of hydrogen and 68 grams oxygen combine what is the percent by mass of oxygen?
The percentage of oxygen is 54,84 %.
How do you measure form grams to atoms?
It depends on the substance. If you have for example, 12 grams of Carbon-12. Then you have 1 mole of carbon 12 which is 6.02 * 1023 molecules of the element, which is equal to 12 grams. One mole of a compound or element is equal to that element's atomic mass in grams.
0.871 moles is how many grams?
Multiply the number of moles by the molecular weight of the compound (or atomic weight for an element) to find the mass in grams.
One mole of which element has the smallest mass?
The mass in grams of 1 mole of the compound (apex)
How do you find the molar mass of a compound using the periodic table?
1) Get the chemical formula to determine the number of each type of atom present in the compound. 2) Multiply the atomic weight (get it from the periodic table) of each element by the number of atoms of that element present your specific compound 3) Do the Sum in unit grams/mole NaCl (1x23 grams/mole Na) + (1x 35.5 grams/mole Cl) = 58.5 grams/mole NaCl
What is gravimetric factor?
A gravimetric factor converts grams of a compound into grams of a single element. For example, we'll find the gravimetric factor of Cl in AgCl. Use the atomic mass of Ag(107.868) and the atomic mass of Cl(35.453) and add them together to get 143.3. Then divide 35.453 by 143.3 to get .2474. .2474 is the gravimetric factor of Cl in AgCl.
Formula for moles?
number of moles = mass of the material/molar mass
