First write out the equation and balance it.
Then look at the ratio of C8H10 to CO2 produced in the reaction (hint: use molecular weights).
For example:
2A = 1B + 1C
where A =4, B=5, and C=3
so, for every 8g of A you get 5g of B
20g of B will yield 20 x 5/8 = 12.5g

How many carbon dioxide molecules are needed to produce 3 molecules of glucose?
Each glucose molecule contains 6 carbon atoms. Thus we need 18 molecules of CO2 to make 3 molecules of glucose.
How many molecules are in 10 grams?
A mole of water is about 18 grams or 18 milliliters of water.A mole of water has 6.022 x 10^23 water molecules. And 10.0 grams of has 3.345 × 10^23 water molecules. And there are 3 total atoms in water molecules, which is H2O. (3.34 × 10^23)*3=1.006 × 10^24 Which means that 1x10^24 atoms are in 10.0 grams of water.
How do you determine the number of molecules of water you swallow from a cup of water?
A cup is 8 fluid ounces. And 8 ounces is about 236.6 grams of water.There are 18 grams of water in one mole of water, and a mole of anything contains Avogadro's number of molecules of that compound. That's 6.02 x 1023 molecules.Our (236.6 grams of water) divided by (18 grams per mole) = 13.14 moles of waterOur (13.14 moles of water)(6.02 x 1023 molecules per mole) = 7.91 x 1024 molecules in the 8 ounce glass of water.We had 8 ounces of water. We converted to grams. Then we looked up water to see how many grams of water there were in a mole of water. Then we found out how many moles we had in our cup of water. Then, because we knew how many molecules of water were in a mole (we know because a mole of anything is Avogadro's number of particles of that substance), we multiply to find out how many molecules of water were in the cup of water.That's how we found that there are 7.91 x 1024 molecules in a cup of water.
How many grams of sugar do cherries have?
18 grams if sugar
How many grams of salt is 18 teaspoons?
That is 90 grams.
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 atoms is 110 grams of CO2?
After figuring out the calculations using the weight of CO2 and Avogadro's number, the total number of atoms in 110 grams of CO2 is 2.34 X 10^18 in sum.
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 carbon dioxide molecules are needed to produce 3 molecules of glucose?
Each glucose molecule contains 6 carbon atoms. Thus we need 18 molecules of CO2 to make 3 molecules of glucose.
How many molecules of water are there in 18 grams of water?
6,022.1023
If you have 6.02 x 1023 molecules of H2O. What is the mass of this sample?
18 grams
What conversion factor will change moles CO2 to Grams CO2?
You would take your grams divided by the FW (formula weight) of the molecule. example: 1g of H2O divided by 18 = .056mol H2O you find the formula weight by adding of the atomic masses of each element O=16 and H=1 1(2)+16=18
