How many grams of H2O do you need to weigh out to have 1 mole of H2O?
To have 1 mole of H2O, you would need to weigh out approximately 18 grams of water (H2O). This is because 1 mole of water molecules (H2O) has a molar mass of about 18 grams/mol (2 grams/mol for hydrogen x 2 atoms + 16 grams/mol for oxygen).
What does 1 liter of oxygen weigh?
1 liter of oxygen weighs approximately 1.43 grams.
How much would a mole of deuterium atoms weigh?
A mole of deuterium atoms would weigh approximately 2 grams. This is because the atomic mass of deuterium is around 2 grams per mole.
Why if sucrose is 51.5 percent oxygen by mass and only 6.4 percent hydrogen by mass is there twice as many hydrogen atoms than oxygen atoms?
The molecular formula of sucrose is C₁₂H₂₂O₁₁. From this formula, we can see that there are 12 hydrogen atoms and 11 oxygen atoms in sucrose. Despite oxygen accounting for 51.5% of the mass and hydrogen only 6.4%, the ratio of hydrogen atoms to oxygen atoms is determined by the molecular formula, not the mass percentages.
WHICH MASS CONTAINS 6.0X10 23 atoms?
The mass containing 6.0x10^23 atoms depends on the element. For example, for carbon-12, 6.0x10^23 atoms would weigh approximately 12 grams.
What is the mass of 0.2 moles of oxygen atoms?
2.000 moles of oxygen atoms weigh 32.00 g. 2.000 moles of oxygen molecules, on the other hand, weigh 64.00 g.
What is the mass in grams of 1mole of oxygen?
The mass of 2.000 mol of oxygen atoms is 32.00 grams.

To have 1 mole of H2O, you would need to weigh out approximately 18 grams of water (H2O). This is because 1 mole of water molecules (H2O) has a molar mass of about 18 grams/mol (2 grams/mol for hydrogen x 2 atoms + 16 grams/mol for oxygen).
What does 1 liter of oxygen weigh?
1 liter of oxygen weighs approximately 1.43 grams.
How many grams do 4.4 x 1022 atoms of potassium weigh. answer in units of grams?
The mass is 2.86 grams but the weight will be 0.028 Newtons.
What is the weight in grams of 3 moles of diatomic oxygen?
One mole of oxygen molecule weighs 32g. Therefore, 3 moles weigh 32 x 3= 96g
How much does one mole of 0 weigh?
1 mole of O (oxygen) weighs 15. 9996 grams. By definition, 1 mole of any element is equal to its atomic weight expressed in grams. 1 mole is equal to 6.02 x 1023 atoms of that element.
How much would a mole of deuterium atoms weigh?
A mole of deuterium atoms would weigh approximately 2 grams. This is because the atomic mass of deuterium is around 2 grams per mole.
Why do 10 oxygen atoms weigh more than 10 carbon atoms?
Because an oxygen atom has 8 protons and 8 neutrons and 8 electrons. A carbon atom has only 6 of each. So 1 oxygen atom weighs more than 1 carbon atom and therefore 10 oxygen atoms weigh more than 10 carbon atoms.
What weighs more 100g of oxygen or 100g of steel?
100 grams is a 100 grams no matter what the material, they weigh the same.
If you knew how many atoms of gold you had how could you figure out what the sample would weigh on a scale?
Yes. One mole (6.02 x 10 to the 23 atoms) would weigh 197 grams.
7.5 times 10 to the 21 uranium atoms equals how many grams?
To convert uranium atoms to grams, you need to know the molar mass of uranium. Uranium's molar mass is approximately 238.03 g/mol. Therefore, 7.5 x 10^21 uranium atoms would weigh approximately 0.625 grams.
