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).
Laboratory data indicates a compound is composed of 43.3 percent sodium 11.3 percent carbon and 45.3 percent oxygen How many grams of each element could be presumed to be present?
Assuming the sample weighs 100 grams, there would be 43.3 grams of sodium, 11.3 grams of carbon, and 45.3 grams of oxygen in the compound according to the given percentages.
How many grams of chlorine are required to combine with 24.4grams of silicon to form silicon tetrachloride?
To find the amount of chlorine needed to combine with silicon to form silicon tetrachloride, first calculate the molar masses of silicon and chlorine (28.09 g/mol and 35.45 g/mol, respectively). As silicon tetrachloride has a 1:4 ratio of silicon to chlorine, this means 1 mole of silicon (28.09 g) will react with 4 moles of chlorine (4 * 35.45 g) to form silicon tetrachloride. Therefore, to find the grams of chlorine needed to combine with 24.4 grams of silicon, calculate (24.4 g Si / 28.09 g Si) * (4 moles Cl * 35.45 g Cl).
How much carbon can 22 grams of carbon dioxide make?
22 grams of carbon dioxide contains 12 grams of carbon. This amount of carbon can combine with 32 grams of oxygen to form 44 grams of carbon dioxide.
Is 15 grams of oxygen gas and 22 grams of nitrogen gas a mixture or a compound?
15 grams of oxygen gas and 22 grams of nitrogen gas together form a mixture, not a compound. A mixture is a physical combination of two or more substances that retain their individual properties, while a compound involves a chemical combination of elements in fixed ratios.
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.
How do you calculate the grams of an element in a specific amount of a compound?
To calculate the grams of an element in a compound, you need to find the molar mass of the element and the compound. Then, use the formula: (mass of element/molar mass of compound) x molar mass of element. This will give you the grams of the element in the compound.
If 6.0grams of element k combine with 17grams of element L how many grams of element k combine with 85grams of element L?

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 are needed to have 5.00 moles?
This depends on the compound.
What additional information is needed to calculate the molecular formula from the percent by mass of each element in a compound?
In addition to the percent by mass of each element, you also need the molar mass of each element. This information allows you to convert the percent by mass into grams and then into moles, which is necessary to determine the empirical formula and subsequently the molecular formula of 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.
How can one determine the empirical formula from percentages of elements in a compound?
To determine the empirical formula from percentages of elements in a compound, first convert the percentages to grams. Then, divide the grams of each element by its molar mass to find the moles of each element. Next, divide the moles of each element by the smallest number of moles to get the simplest whole number ratio. This ratio represents the empirical formula of the compound.
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
How many grams of o2 are needed to combine with 6.85g of P?
To find the amount of O2 needed to combine with 6.85g of P, we first need to balance the chemical equation for the reaction between P and O2 to determine the mole ratio. Once we have the mole ratio, we can calculate the amount of O2 needed in grams using the given mass of P.
