1. Given: mass = 0.334g of C2H6, CAtomicWeight = 12.01, HAtomicWeight = 1.008
Required:
a. Molar Mass of Ethane
b. Number of molecules of C2H6 in 0.334g of C2H6
Formula:
a. (n = (2 x CAtomicWeight) + (6 x HAtomicWeight)
b. mass x (1 mole / a ) x (6.022x1023 molecules / 1 mole)
Solution:
a. Molar Mass of Ethane
n = (2 x 12.01) + (6 x 1.008)
n = 24.02 + 6.0498
n = 30.0698
b. Number of molecules
n = 0.334 x (1 mole / 30.0698 g) x (6.022x1023 molecules / 1 mole)
n = 6.689x1021 molecules
FINAL Answer: The are 6.689x1021 molecules in 0.334g of Ethane

Are carbon dioxide and carbon tetrachloride the only two non polar molecules?
No, there are many other nonpolar molecules besides carbon dioxide and carbon tetrachloride. Examples include methane, ethane, and diatomic gases like nitrogen and oxygen. Nonpolar molecules generally have more symmetric structures, with balanced distribution of electrons.
How many molecules are present in 2c6h12o6?
12 molecules of carbon 24 of hydrogen 12 of oxygen
How many molcules are present in 42.0g of Cl2?
To find the number of molecules in 42.0g of Cl2, you first need to determine the number of moles using the molar mass of Cl2 (71 g/mol). Next, you can use Avogadro's number (6.022 x 10^23 molecules/mol) to convert moles to molecules. Therefore, in 42.0g of Cl2, there would be approximately 3.56 x 10^23 molecules.
How many molecules of H2 are present in 0.175 moles of H2?
0.175 X Avogadro's Number = about 1.05 X 1023.
How many moles are present in 1.21 molecules of HBr?
To find the number of moles in 1.21 molecules of HBr, divide the number of molecules by Avogadro's number (6.022 x 10^23 molecules/mol). Thus, 1.21 molecules of HBr is approximately 2.01 x 10^-24 moles.
How many molecules of ethane are present in 0.334 grams of ethane?
To find the number of molecules of ethane in 0.334 grams, you would first convert the mass to moles using the molar mass of ethane. Then, you can use Avogadro's number (6.022 x 10^23 molecules/mol) to find the number of molecules in that number of moles.
How many carbon dioxide molecules will be formed in two ethane molecules?
Ethane does not have any molecule of carbon dioxide. However when ethane undergoes combustion then two molecules of carbon dioxide are formed (as ethane contains two carbon atoms).
How many molecules of ethane are present in 64.28 liters of ethane gas (C2H6) at STP?
at STP 1 mole occupies 22.4 litres. 64.28 / 22.4 is 2.8696428 moles. Multiply this by avagadro's constant (6.022*10^23) gives 1.7281x10^24 molecules
How many molecules are in 60 g of ethane?
To determine the number of molecules in 60 g of ethane, you need to first calculate the number of moles of ethane using its molar mass (30 g/mol). Then, you can convert moles to molecules using Avogadro's number, which is 6.022 x 10^23 molecules/mol.
How many carbon dioxide molecules will be formed from two ethane molecules?
I am presuming that you are asking how many carbon dioxide (CO2) molecules will be formed when two ethane (C2H6) molecules burn in a plentiful supply of oxygen. The following balanced equation is that of the burning of ethane in a plentiful supply of oxygen: C2H6 + 3.5O2 -----> 2CO2 + 3H2O. The number before each of the molecules in the equation tells us how many there are in this reaction. This means that for every one ethane molecule that is burnt, two carbon dioxide molecules are produced.
What is the name of the reaction in which many ethane molecules combine together?
You think probable to polymerization.
How many carbon atoms are contained in 5.50 gms of ethane?
30 g of ethane will have 6.023 x 1023 molecules of ethane So, 5.5 g will have 1.104 x 1023 molecules of ethane Since there are two carbon atoms, in one molecule of ethane, 5.5 g of ethane will have 2.208 x 1023 atoms of carbon.
How many molecules are present in 3 moles of methanal?
The reaction is :- 2C2H6 + 7O2 ----------> 4CO2 + 6H2O When one mole ethane is combusted 7/2 moles of oxygen are used. When 3 moles of ethane are combusted 3 x 7/2 moles of oxygen used. No. of oxygen molecules consumed =6.022 x 1023 x7/2= 21.077 x 1023=2.107 x 1024 molecules.

How many molecules of ethane gas C2H6 are in 15 grams of the compound?
To calculate the number of molecules in 15 grams of ethane (C2H6), first find the molar mass of C2H6, which is 30.07 g/mol. Next, calculate the number of moles in 15 grams using the formula: moles = mass / molar mass. Finally, use Avogadro's number (6.022 x 10^23 molecules/mol) to convert moles to molecules.
How many c2h6 molecules are contained in 51.2 moles of ethane?
The chemical formula for ethane is C2H6 and there is 6.022 * 10^23 molecules in every mole. So to find your answer simply multiply 6.022 * 10^23 by 51.2 which gives: 3.083 X 10^25
