A molecule of alkene has the chemical formula C3H4. How many carbon-carbon double bonds are present in the molecule?
One carbon-carbon double bond is present in a molecule of alkene with the chemical formula C3H4.
How many molecules of water does a 50g sample of H2O have?
A 50g sample of H2O contains approximately 2.78 x 10^24 molecules of water. This is calculated by first converting the mass to moles, then using Avogadro's number to determine the number of molecules present in that many moles of water.
How many moles of C2H6O in 10.0 grams?
For this you need the atomic (molecular) mass of C3H4. Take the number of grams and divide it by the atomic mass. Multiply by one mole for units to cancel. C3H4=40.0 grams10.0 grams C3H4 / 40.0 grams = .250 moles C3H4
How many moles of water molecules H2O are present in a 27 gram sample of water?
There are 1.5 moles of water molecules in a 27 gram sample of water. This is calculated by dividing the mass of the sample (27 grams) by the molar mass of water (18 grams/mol).
How many molecules are in sample 57.45 CF2Cl2?
To calculate the number of molecules in a sample, you need to know the mass of the sample and the molar mass of the compound. Then you can use Avogadro's number (6.022 x 10^23) to convert from grams to molecules.
How many carbon atoms are present in C3H4?
There are 3 Carbon atoms in C3H4. The numbers following the Element names (Like C, or H, or Na) is the amount of atoms in the compound. So there are 3 Carbon atoms and 4 Hydrogen atoms. That is incorrect the answer would be 4.53 x 1023 carbon molecules

One carbon-carbon double bond is present in a molecule of alkene with the chemical formula C3H4.
How many carbon-carbon double bonds are present in a molecule of alkene with the chemical formula C3H4?
H2C = C = CH2 is C3H4 and it has 2 C-carbon double bonds.

How many moles of water molecules H2O are present in a 27 gram sample of water?
There are 1.5 moles of water molecules in a 27 gram sample of water. This is calculated by dividing the mass of the sample (27 grams) by the molar mass of water (18 grams/mol).
How many moles of N2O molecules are present in a sample that contains 5.23 moles of nitrogen atoms?
Since each N2O molecule contains 2 nitrogen atoms, the number of moles of N2O molecules would be half of the moles of nitrogen atoms. Therefore, in this case, there would be 2.615 moles of N2O molecules present in the sample.
A sample of water contains 3.6 moles of hydrogen atoms How many molecules of water are present in this sample?
Each water molecule contains two hydrogen atoms. Therefore, the number of water molecules present in the sample can be calculated by dividing the number of hydrogen atoms by 2. In this case, 3.6 moles of hydrogen atoms corresponds to 1.8 moles of water molecules. This is equal to approximately 1.08 x 10^24 water molecules.
How many molecules are in sample 57.45 CF2Cl2?
To calculate the number of molecules in a sample, you need to know the mass of the sample and the molar mass of the compound. Then you can use Avogadro's number (6.022 x 10^23) to convert from grams to molecules.
How many molecules are contained in a 5.20 g sample of dimethylmercury?
The answer is 1,357.10 ex.23 molecules.
How many molecules are present in a sample of this compound that contains 3.10 moles of 3 methyl 2 butanol?
To determine the number of molecules in a sample of a compound, you can use Avogadro's number, which is 6.022 x 10^23 molecules/mole. In this case, if you have 3.10 moles of 3-methyl-2-butanol, you would multiply the moles by Avogadro's number to find the number of molecules in the sample.
How many lb-moles of substance are present in the given sample?
To determine the number of lb-moles in a sample, divide the weight of the sample in pounds by the molecular weight of the substance. This will give you the number of lb-moles present in the sample.
