How many atoms in 1 mole?
There are 6.022 x 10^23 atoms in 1 mole of a substance. This number is known as Avogadro's number and represents the number of particles in one mole of a substance.
Substance X is a molecular compound and is not an acid Based just on this information what can you determine about substance X?
From the information provided, we can determine that substance X is not an acidic compound. However, without more specific details about its chemical composition, we cannot make any further conclusions about its properties.
How many grams of the substance in the molecule C2O2H4 would be equal to 1 mol of the substance?
The mass in grams of a substance that equals one mole of that substance is the molecular weight of the substance, which can be found by adding the atomic weights of all the atoms in the molecule. For C2O2H4, the molecular weight would be (12 x 2) + (16 x 2) + (1 x 4) = 60 g/mol.
She measured 5.0 kg of substances x at noon Tuesday shaunameasured 1.25 kg of substance x what is the half- life of substance x?
If substance x decays by emitting 100% gas which escapes leaving no residues, then the half-life is half the time elapsed since noon Tuesday If substance x contains some components which decay by say, K capture (the nucleus captures one of its orbiting electrons) with practically no change in mass, then the picture is complicated because it may have a short half-life, not detectable by weighing. For this reason half-life is not determined or defined by weight. It is defined by the proportion of the original atomic species which remains after some interval of time, possibly determined by, say, chemical or spectroscopic analysis.
How many atoms are there in 250 mol Si?
1 mole of anything is 6.022 x 1023 atoms or molecules of that substance. Thus, 2500 atoms of a substance is about 4.151 x 10-21 moles of that substance.
Substance x has a mass of 6.0g and a volume 3.2ml what is the density of this substance?
The density of Substance X is 1.875 g/mL
What is the equation to calculate the percentage of each substance in a mixture?
(percentage)x(how much of the substance)+(percentage)x(how much of the substance)=(total percentage)(total of substance)
Grams to formula units?
It depends on the substance and its molar mass.In order to convert from grams to formula units, you must first convert grams to moles, then moles to formula units (grams --> moles --> formula units).1. Divide the mass (g) of the given substance by the substance's molar mass.2. Multiply the number of moles found in Step 1 (above) by Avogadro's number (6.022 x 1023).---- Mass substance ----- X 6.022 x 1023 formula unitsMolar mass substanceCONVERSION FACTORMass (g) substance x 1 mol substance ------- x ----- Avogadro's number/////////////////// molar mass (g) substance ------------ 1 mol substance

How many particles are in 1.57 moles of substance?
In one mole of a substance, there are 6.022 x 1023 particles. So, 1.57 moles x (6.022 x 1023 particles/1 mol) = 9.45 x 1023 particles.
How do you atoms to grams?
You find the number of atoms from the number of grams of a given substance by:Find the Moles of the Substance by multiplying the grams of the substance by the molar mass of the substance. ( Molar mass equals mass of substance per 1 mole of substance.)Grams x Molar Mass of Substance = Moles of SubstanceTake the moles of the substance and multiply it by Avogadro's Number (the number of atoms in 1 mole of substance, or simply 6.022x1023).Moles of Substance x Avogadro's Number (6.022x1023) = atoms of Substance
What is substance x in the series of enzymes catalyzed reactions x-y-z-a?
A substrate
What substance can corrode stone and metal?
alkali ?? x
What is the weight of a sphere?
The answer will depend on what the sphere is made of and where it is weighed. But regardless of the substance and the planet it's on, you can always be sure that it weighs (4/3) x (pi) x (Radius)3 x (density of the substance) x (local acceleration of gravity).
what is the amount of mass given in a given volume of air?
Density of substance = mass of substance / volume mass of substance = density x volume
