How many grams of sodium are in a 1 mole sample of sodium?
The molar mass of an element corresponds to the atomic mass of the element (found on the periodic table). The atomic mass of Sodium-Na is 22.990 g, which is also the molar mass of Na. So for 1 mole of Na, there are 22.990 grams of Na. If we had 3 moles of Na, then we would simply multiply the molar mass by 3.
How many grams of NH3 can be produced from 4.33 mol of N2 and excess H2. Express your answer numerically in grams.?
The mass of ammonia is 147,5 g.
What is the molar mass in grams of mole of an element equal to?
weight...'
How do you calculate empirical ratio?
Start with the number of grams of each element in a problem. Convert that with mass of each element to moles. Divide each mole value by the smallest number of mole then round it to the nearest whole number.
If 6.02 x 1023 atoms of element y have a mass of 83.80 g what is the identity of y?
6.02 x 1023 atoms of an element is one mole of that element. The mole, based on Avagadro's number, is defined as the number of Carbon atoms that would have a mass of 12 grams. This is a scaling factor related to atomic mass. Krypton has an atomic mass of 83.8, so if a mole of an unknown element is 83.8 grams, then that element is Krypton.
Chemists define gram atomic mass as the number of grams of An element numerically equal to the?
atomic weight
How many grams are required to have 0.100 mol of C2H5OH?
2.430g. That's one tenth the number of grams in one mole of Mg, which would be 24.30, which is also its atomic weight. No, that is not a coincidence. Atomic weight of an element is always equal to the number of grams of an element in a mole of the same element.
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.
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).
Average mass of one atom of an element?
what is the atomic mass of an element : atomic mass is equal to the number of protons and number of neutrons present in an element
How do you find the moles of a given element?
One takes the atomic mass of that element (the number under the element on a periodic table, measured in amu). That number is the number of grams of the element it takes to make one mole. in other words:X grams (of element)(Atomic Mass of element)= --------------1 mol (of element)
How many micrograms in 25 grams?
There are 1 million micrograms in a gram, so there are 25 million micrograms in 25 grams. To put the number numerically: 2.5x10^7=25000000
How many grams of sodium are in a 1 mole sample of sodium?
The molar mass of an element corresponds to the atomic mass of the element (found on the periodic table). The atomic mass of Sodium-Na is 22.990 g, which is also the molar mass of Na. So for 1 mole of Na, there are 22.990 grams of Na. If we had 3 moles of Na, then we would simply multiply the molar mass by 3.
How does a mole of atoms of one element compare to a mole of another element?
Type your answer here...they all be equal to that element's atomic mass in grams.
How do you convert grams to atoms with the avogadro's number?
(grams) x (6.02 x 10^23) / (mass number of specific element in grams)
How do you convert from grams to atoms and from mass to atoms?
1 atomgram of a chemical element has 6,02214129(27)×1023 atoms. 1 atomgram=atomic weight of a chemical element exprimed in grams.
Does 23 g of sodium and 238 g of uranium have equal number of atoms in them?
dose 23 grams of sodium and 238 grams of uranium have equal number of atoms in them
