Since the molar mass (grams per mole) of H2O is 18.02, the grams of H2O in 4 moles is 72.08g.
To find the mass of CO2 produced, first calculate the moles of C2H4 using its molar mass. Then, use the balanced equation to determine the moles of CO2 produced per mole of C2H4 reacted. Finally, convert moles of CO2 to grams using the molar mass of CO2.
the rule for solving amount of molecules is N(molecules)=6x10^23 x n(amount of mole) therefore there are 6x10^23 molecules in 1 mole of anything or in this case of H20
The molar mass of water (H2O) is approximately 18.02 g/mol. To find the number of moles in 40.0 g of water, you would divide 40.0 g by the molar mass of water. This would give you approximately 2.22 moles of water.
When 120g of glucose is converted to ATP in muscle cells, it produces 72g of water and 264g of carbon dioxide. This process involves the breakdown of glucose through cellular respiration, where glucose is oxidized to produce energy (ATP), water, and carbon dioxide.
There are four molecules of water in 4H2O. One molecule of water is written as H2O. The subscript 2 tells you that there are two H(hydrogen) atoms. Since there is no subscript after the O there is one O(oxygen) atom. Now back to 4H2O. The coefficient 4 tells you there are four molecules of H2O. Therefore there are eight H(hydrogen) atoms and four O(oxygen) atoms.
45 grams H20 x (1 mole H20/18 grams H2O) x (6.02E23 molecules H20/1 mole H2O) the grams H2O and moles H2O cancel out. When you punch it into your calculator, the answer comes out to: =1.505E24 molecules H2O
Water has a molecuar mass of 18. This means it weights 18g per a mole. The molecular formula for water is H20. Your answer for how many moles in 1000 grams of water is 55.5084351.
Ratio of O2 to H20 after balancing equation is 1:2. 1:2 1.25:x.by cross multiplication x is 2.5 Mole =mass/mr.2.5×18(mr of h20) we get 27grams.
For this you need the atomic (molecular) mass of H2O. Take the number of grams and divide it by the atomic mass. Multiply by one mole for units to cancel. H2O= 18.0 grams500.0 grams H2O / (18.0 grams) = 27.8 moles H2O
To find the mass of CO2 produced, first calculate the moles of C2H4 using its molar mass. Then, use the balanced equation to determine the moles of CO2 produced per mole of C2H4 reacted. Finally, convert moles of CO2 to grams using the molar mass of CO2.
in order to find the mass of H20 you need the molar mass which is 18.01g/mol and to calculate the mass you just multiply by the number of moles. 18.01 * .20 = 3.60g
Instead of waiting for the answer, I ended up solving it. lol 300grams of H20 X 110grams of KNO3/100 grams of H20 = 330 grams of KNO3 The grams of H20 both cancel out and leave you with 330 grams of KNO3 Containing the solubility of KNO3. At 60 degrees celsius the KNO3 grams were 110, which is (over) / 100grams of H20. Hope this helps with this workbook problem :)
Each mole of a substance contains 6.022 E23 molecules or atoms of that substance. Four moles of H2O will contain 2.4088 E24 molecules.
the rule for solving amount of molecules is N(molecules)=6x10^23 x n(amount of mole) therefore there are 6x10^23 molecules in 1 mole of anything or in this case of H20
To determine how many hydrogen atoms are in 301 grams of H2O, we need to consider the molar mass of water (H2O). The molar mass of water is approximately 18 grams/mole. Since the molecular formula of water is H2O, it contains 2 hydrogen atoms. Using this information, we can calculate the number of moles in 301 grams of water and then determine the number of hydrogen atoms present.
to get the answer, take the mass you have divide by the molecular mass of the compound which in water's case happens to be 18g. 18g x 1mol/18g = 1 mole or 6.022x1023 molecules of H2O
There are three
