What else can I help you with?
Contains the fewest sodium atoms is it 1 mol sodium oxide 45g of sodium floride 50g of sodium chloride and 1 mole sodium nitrate.?
1 mole of sodium oxide contains the fewest sodium atoms because it contains 1 mole of sodium atoms. Each of the other compounds (45g of sodium fluoride, 50g of sodium chloride, and 1 mole of sodium nitrate) contains more than 1 mole of sodium atoms.
Who has more electrons nitrogen calcium oxygen or sodium?
Calcium has the most electrons. Nitrogen has 7, calcium has 20, oxygen has 16 and sodium has 11 electrons.
Which element is more likely to react with oxygen Sodium or Calcium please explain if you can thank you?
Sodium. Sodium is more reactive than calcium, because sodium has one valence electron whereas calcium has two valence electron. It is easier to lose one electron and react with oxygen and form sodium oxide, compared to losing two electrons and from calcium oxide.
Is sodiums weight about 3 grams?
You can have any weight of sodium you want down to 0.00000000000000000000003847 grams, the approximate weight of one sodium atom
What atom has the largest atomic radius sodium or oxygen?
Sodium has a larger atomic radius than oxygen. This is because sodium has one more energy level (shell) of electrons compared to oxygen, leading to a greater distance between the nucleus and the outermost electron.
Which has more mass a mole of potassium or a mole of sodium?
A mole of potassium. Sodium weighs 22.990 g/mol while potassium weighs 39.068 g/mol.
What will weigh more a mole of Na or a mole of S?
A mole of S (32 g) weighs more than a mole of Sodium Na (23 g)

1 mole of sodium oxide contains the fewest sodium atoms because it contains 1 mole of sodium atoms. Each of the other compounds (45g of sodium fluoride, 50g of sodium chloride, and 1 mole of sodium nitrate) contains more than 1 mole of sodium atoms.
What weighs more a mole of sucrose or a mole of water?
A mole of water weighs more than a mole of sucrose. This is because the molar mass of water (18 g/mol) is less than the molar mass of sucrose (342 g/mol).
Who has more electrons nitrogen calcium oxygen or sodium?
Calcium has the most electrons. Nitrogen has 7, calcium has 20, oxygen has 16 and sodium has 11 electrons.
When you have 46 grams of sodium react with 160 grams of oxygen how many moles of sodium oxide are obtained?
The equation for the reaction is 4 Na + O2 -> 2 Na2O. This shows that, for complete reaction, one mole of oxygen is required for each four gram atomic masses of sodium. The gram atomic mass of sodium is 22.9898; therefore, 46 grams of sodium constitutes 2.00 moles of sodium, to more than the justified number of significant digits. The gram molecular mass of diatomic oxygen is 31.9988; therefore 160 grams of oxygen constitutes 5.000 moles of diatomic oxygen, to more than the justified number of significant digits. This is well over the minimum amount of oxygen required for complete reaction of all the sodium present. Each two gram atomic masses of sodium produces one gram formula mass of sodium oxide; therefore, the number of gram formula masses of sodium oxide produced is 1.00, to at least the justified number of significant digits.

What does one molecule of ammonium nitrite contain?
In chemistry and physics, a mole is an amount of a substance equal to its molecular weight in grams. For example, oxygen has an atomic weight of 16. Hydrogen has an atomic weight of 1. A molecule of water, H2O, has two atoms of hydrogen and one atom of oxygen. So its molecular weight is 1+1+16=18. So a mole of water weighs 18 grams. (And since 1 cubic centimeter of water weighs 1 gram, a mole of water would be 18 cubic centimeters.) A mole of ammonium nitrate, NH4NO2, weighs 34 grams. (14+1+1+1+1+14+16+16=34) Other useful facts about moles of gases: The atoms of many gases travel around in pairs. That is, each molecule contains 2 atoms. The hydrogen molecule is H2; the oxygen molecule is O2; and the nitrogen molecule is N2. So a mole of hydrogen gas is 2 grams; a mole of oxygen gas is 32 grams; and a mole of nitrogen gas (atomic weight 14) is 28 grams. It so happens that all gases at the same temperature and pressure contain the same number of molecules. If we take a mole of any gas at normal temperature and pressure, we find that it occupies 22.4 liters of space. So, 22.4 liters of hydrogen is one mole and it weighs 2 grams. And 22.4 liters of oxygen is one mole and it weighs 32 grams. And 22.4 liters of nitrogen is one mole and it weighs 28 grams. Air is a mixture of 80% nitrogen molecules and 20% oxygen molecules. 22.4 liters of air is one mole and it weighs 29 grams. Now you can see why a hydrogen balloon will rise in air. Each mole of hydrogen in the balloon weighs only 2 grams, while each mole of the surrounding air weighs 32 grams. Now you can calculate how big a balloon you would need to fly. Some more common gases: Carbon has an atomic weight of 12, chlorine of 35, and fluorine of 19. A mole of carbon monoxide, CO, weighs 28 grams. (12+16=28) This is very close to the weight of air, so this poisonous gas tends to hang around where it is released. A mole of carbon dioxide, CO2, weighs 44 grams. (12+16+16=44) This is much heavier than air, and, while it is not poisonous, it often accumulates in low spots like abandoned wells and cisterns, pushing out all of the air. A mole of methane, CH4, weighs 16 grams. (12+1+1+1+1=16) Notice that it, like water vapor (18), is lighter than air and will rise. A mole of Freon 12 (used in car air conditioners), CCl2F2, weighs 120 grams. (12+35+35+19+19=120). This is so much heavier than air that it is unlikely that any significant amount could ever reach the altitude of the ozone layer.

Which atom will form an ion sodium or oxygen?
sodium
Is one mole of cadmium heavier than one mole of gold?
No, one mole of gold is heavier than one mole of cadmium. Gold has a higher molar mass than cadmium, which means that one mole of gold contains more atoms and therefore weighs more than one mole of cadmium.
Is the mass of 1 mole of oxygen and 1 mole of S same?
No, the (molar) mass (ie. the mass of one mole) is different by factor 2.004:Oxygen atom (O)15.999 g/mole O2,Oxygen molecule (elemental gas, O2) 31.998 g/mole O2Sulfur atom (S) 32.06 g/mole S,Sulfur molecule (bright yellow solid, S8) 256.48 g/mole S8,Sulfur molecule (S2) 64.12 g/mole S2 (there are more than 20 other allotropes)
