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?
Oxygen atoms weigh more than Hydrogen atoms.
How much does CO2 weigh in grams?
carbon= 12.01 oxygen=16*2 12.01+32=44.01 CO2
What is the mass of 175 atoms of gold?
equation: g= 175 atoms x 1 mol/6.02x10^23 x 196.97g/1 mol ---> 175 atoms of gold weigh 5.73x10^-20 grams.
What is the mass of 7.8 x 1018 carbon atoms?
3.011 x 1023 atoms of carbon will weigh about 6 grams One mole of carbon atoms weighs 12.011 grams, and there are 6.022 x 1023 atoms in a moles. So you have half as many atoms, so the mass would be half as much or 6.0055 grams to be precise.
How much does a nickel weigh in grams?
All U.S. nickels weigh 5 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.
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?
Oxygen atoms weigh more than Hydrogen atoms.
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.
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 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.
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 many grams do 1.8 moles of oxygen weight?
1 mole of oxygen weighs 16 grams. So, 1.8 moles would weigh 1.8 x 16 = 28.8g
How much do 4.81025 atoms weigh?
There is no such substance. There cannot be part of an atom (indicated by the decimal), there are only whole number of atoms. And even if you did say, how much does 4 (or whole number) atoms weigh, it could not be determined. This is because the particular element that defines the atoms has to be stated. Four atoms of oxygen will weigh differently than four atoms of lithium. Therefore, it cannot be answered.
What is the percentage of oxygen in nitrous oxide?
There is one atom of oxygen per molecule of nitrous oxide (N2O). Therefore, using atomic percent, it is 1/3 oxygen.However, the mass of oxygen and nitrogen are different, and so the mass percent of oxygen is not 1/3. Nitrogen atoms weigh 14 grams/mole, and oxygen atoms weigh 16 grams per mole, so N2O weighs 44 grams per mole, so the percent oxygen is:16 ÷ 44 *100% = 36.36% by mass.
Why does mercury weigh more when heated with oxygen?
It's because atoms of oxygen join atoms of mercury, forming new chemical -- mercury oxide HgO. Since it consists of two elements, its weight will be bigger.
How many grams do 4.6 x1025 atoms of cu weigh?
I assume you mean 4.6 X 10^25 atoms. This is the conversion. 4.6 X 10^25 atoms Cu ( 1mol Cu/ 6.022 X 10^23 )( 63.55 grams Cu/ 1 mol Cu ) = 4854.37 grams Cu
