What mass of CO2 is produced when 50.0 g of C2 H4 reacts completely in C2 H4 plus 3 O2 equals 2 CO2 plus 2 H20?
C2H4 + 3O2 -> 2CO2 +2H2O 50.0 grams C2H4 (1 mole C2H4/28.052 grams)(2 mole CO2/1 mole C2H4)(44.01 grams/1 mole CO2) = 157 grams CO2 produced
How many moles are in 40.0g of h20?
Since moles = mass/molar mass then the number of moles is 40.0/(1+1+16) = 2.22mol to 3sf
How many molecules of H2O equals 1 mole of H2O?
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
If all of the 120g of glucose are converted within muscle cells to energy ATP how many grams of H20 will be produced how many grams of C02 will be produced?
If all of th 120 g of glucose are converted to energy, how many grams of h2o and co2 will be produced?
How many grams of ethylene are needed to react with 0.132 mol of H20?
C2H4 + H2O --> C2H5OHReaction balanced at 1:1:1 mole of each compound, so you'll need 0.132 mol C2H4 and this is equal to:0.132 (mol C2H4) * 28 (g/mol C2H4) = 3.696 g C2H4 = 3.70 g C2H4
How many molecules are in 4.21 grams of water?
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
How many moles of water are there in 1000 grams of water?
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.
What mass of CO2 is produced when 50.0 g of C2 H4 reacts completely in C2 H4 plus 3 O2 equals 2 CO2 plus 2 H20?
C2H4 + 3O2 -> 2CO2 +2H2O 50.0 grams C2H4 (1 mole C2H4/28.052 grams)(2 mole CO2/1 mole C2H4)(44.01 grams/1 mole CO2) = 157 grams CO2 produced
When 1.25 moles of oxygen reacts with excess hydrogen gas how many grams of water is produced?
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.
How many moles are in 40.0g of h20?
Since moles = mass/molar mass then the number of moles is 40.0/(1+1+16) = 2.22mol to 3sf
How many molecules in 0.4 moles of h20?
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.
How many moles are present in 500.00 g of H2O?
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
Can you show me how to calculate the of moles in 0.037g H2O This is the mass of water lost after heating.?
.037g x 1 mole of H2O / 18.02g H2O= .00205 moles H20 this is a simple factor label problem in which you multiply the number of grams by the number of grams per mole. Thus, the GRAMS cancel and you are left with moles. 18.02 is the molecular weight of H2O; 1.01+1.01+16= 18.02 g/mol
How many grams of KNO3 will dissolve in 100 g of water at 30 degrees Celsius?
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 :)
How many molecules of H2O equals 1 mole of H2O?
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
If all of the 120g of glucose are converted within muscle cells to energy ATP how many grams of H20 will be produced how many grams of C02 will be produced?
If all of th 120 g of glucose are converted to energy, how many grams of h2o and co2 will be produced?
