What is the atomic mass of Hydrogen Nitrogen and oxygen?
hydrogen-1g nitrogen-14g oxygen-16g
What is the total number of atoms in water?
it depends on how much water you have. but the density is 1g/cm^(3) .
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 many elements does sodium hydroxide have?
Sodium hydroxide has the formula NaOH and it contains three atoms, one each of Sodium, Hydrogen and Oxygen.
1 pound of hydrogen is How many cubic feet?
One pound = 0.453592kg. One Mole of H = 1g 0.453592kg of H = 453.592 mole of H According to the ideal gas law, one mole of gas will occupy 22.4 liters as stp. One pound of H will occupy 10,160.2608 liters, or 358.806 cubic feet. Be careful. Most applications of this calculation will deal with hydrogen gas, which has two hydrogen atoms per molecule at standard temperature and pressure. In such cases, divide the volume calculated above by two.
How many amu 1g of substance has?
1.66
Is there such thing as 6.0221023 atoms equal to 1g?
Yes. One mole (6.022x1023) of hydrogen atoms would have a mass of about 1g.
If 1g of hydrogen contains 602000000000000000000000 atoms of hydrogen what is mass of 1 hydro gon atom?
1
How many atoms are in 1 amu?
An atomic mass unit equates to 1.66053892e-24 grams.
How many atoms are in 1g of hydrogen gas?
Amount of hydrogen gas = 1.0/2.0 = 0.50mol In each molecule of hydrogen gas there are two hydrogen atoms. 1 mol of H2 contains 6.02 x 1023 molecules (avogadro constant). Number of H atoms = 2 x 0.50 x 6.02 x 1023 = 6.02 x 1023
How many moles of hydrogen in 1g?
About 1 mole
How many atoms in 1g H2?
1 gram H2 (1 mole H2/2.016 grams)(6.022 X 1023/1 mole H2) = 3 X 1023 atoms of hydrogen gas =========================
How many ounces equals a mole of water?
In chemisty metric weights are used rather than imperial, it makes things a lot simpler. Mole's are easy to calculate all you need to remember is that 1mol is equal in grammes to the molecular mass of the molicule. So water is 2 Hydrogen atoms each of 1.008 atomic mass unit (AMU) and 1 Oxygen atom of 15.999 AMU. So (2x1.008)+15.999=18.015 AMU therefore one mol of water is 18.015g. Two points though. 1: As it is difficult to weigh out to one thousandth of a gramme you often round up especially when using water as volume is often used instead as 1Cm3 is appprox 1g 2:AMU's are approximate weights as different isotopes have different AMU's, therefore 1 mol of water is approx 18.015g.
What is the mass of 1000amu of iron in gram?
1g = 6 x 1023 amu (near enough). The maths from there is easy
What is the number of hydrogen atoms in 2 moles of sulfur hexahydride?
The answer is 72,24.1023 atoms of H. Hydrogen - 1 mole = 1g (atomic mass '1'). 1 (hydrogen atomic number) x 2 (specified moles) x 6 (hydrogen atoms in SH6) x (6.02 x 10^23) (avogadro's number). Avogadro's number is used in working out molarity, using the above equation. But I suppose that you think to SF6, sulfur hexafluoride.
What is the atomic mass of Hydrogen Nitrogen and oxygen?
hydrogen-1g nitrogen-14g oxygen-16g
How many electrons are there in 1g of hydrogen gas?
The gram atomic mass of hydrogen is close to 1, so that 1 g of the gas contains one mole of hydrogen atoms. Each atom contains 1 electron, so that the stated amount of gas contains Avogadro's Number of electrons, 6 X 1023 to the justified number of significant digits.
