How many atoms in 1mg of As?
First you need to organize what you need to determine the number of atoms in 1 mg of As. You need to know the following:1 mol As = 74.92160g As (from the periodic table)1 mol As = 6.022 x 1023 atoms As (Avogadro's number)1000mg = 1g As (conversion from mg to g)Now we start the calculations:1) Convert mg to g.1mg As x (1g/1000mg) = 0.001g As2) Convert g As to moles As0.001g x (1mol As/74.92160g As) = 1.3 x 10-5mol As3) Convert mole As to atoms of As1.3 x 10-5mol As x (6.022 x 1023 atoms As/1mol As As) =7.8 x 1018 atoms AsSo, the answer to your question, is that 1mg of As has 7.8 x 1018 atoms As
How are reactant atoms and molecules different to their products atoms and molecules?
Well the reactants are what you start off with and the products are what you end up with. So the products are the reactants combined.
Number of moles and number of atoms in a 214 gram sample of silver?
According to the periodic table, silver (Ag) has an atomic mass of about 108 grams per mole. If you have 802 grams, set up a direct proportion where 108/1=802/x and solve for x. You get about 7.43 moles of silver.
How many potassium atoms are in the reactants of the chemical reaction?
The same number you started with. In every chemical reaction the total number of atoms at the start is the same as the number of atoms at the end.
In a chemical reaction the number of atoms of reactants and products must?
I know that this probably isn't the answer that you were looking for but its a start the answer to this question is one of four different answers choose the one that you think is right. A) The same as the number of atoms in the reactants B) Less than the number of atoms in the reactants C) Greater than the number of atoms in the reactants D) The same as the number of molecules in the reactants
What is hypothetico-deduction reasoning?
When faced with a problem, you start with a general theory of all possible factors that might affect an outcome and deduce from it specific hypothesis (or predictions) about what might happen.
What is hypothetico-deductive reasoning?
Hypothetico-deductive reasoning is a method of forming and testing hypotheses to explain a phenomenon. It involves proposing a hypothesis, making predictions based on that hypothesis, testing those predictions through experiments or observation, and then revising the hypothesis based on the results. This process helps scientists systematically evaluate and refine their understanding of the natural world.

How many oxygen atoms are needed to start photosynthesis reaction?
2 atoms
What is the balanced chemical equation for CaCO3 to CaO plus CO2?
The equation is already balanced:CaCO3(s) --> CaO(s) + CO2(g)ExplanationA balanced chemical equation is one where the number of atoms on both sides are equal. Chemical equations must be balanced because there is only a rearrangement of atoms in a reaction so the number of atoms you start off with must be the same as the number of atoms you end up with.If we take a look at the equation, we can see that there is 1 calcium atom, 1 carbon atom and 3 oxygen atoms present on both sides. As the number of these atoms on both sides are equal, the equation is balanced.
How many atoms of LiBr would you have if you start with 1.25 moles What is the answer and how did you get it?
Not atoms of LiBr; formula units is correct.1 mol = 6,022 140 857.10e23 (molecules, atoms, ions); this is the Avogadro number.6,022 140 857.10e23 x 1,25 = 7,52767607125.10e23 formula units of LiBr
What 3 numbers add up to 92?
Start with 1, 2 as the first two numbers. Subtract those numbers from the original number. The remaining number is one possible outcome. Dont be a dingus next time.
