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 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.
What is the covalent name of C2H6?
The covalent name of C2H6 is ethane.
How many grams of oxygen gas will react with 77.28 grams of ethane in 2 C2H6 plus 7 O2 equals 4 CO2 plus 6H2O?
First, find out how many moles of C2H6 that you have: Carbon is 12 grams per mole, and H is 1 gram per mole, so C2H6 is (2*12 + 6*1)grams = 30 grams per mole. So you have (77.28/30 = 2.58) moles. Every 2 moles of C2H6 reacts wilth 7 moles of O2 so it will react with 7/2*2.58 moles = 9.02 moles of O2.O2 is 32 grams per mole, so (9.02 moles)*(32 grams/mole) = 288.64 grams.
How many moles of oxygen are required to burn 22.4 liters of ethane gas C2H6 at standard conditions?
For the complete combustion of ethane (C2H6), each molecule of ethane reacts with 3.5 molecules of oxygen (O2). At standard conditions, 22.4 liters of any gas corresponds to 1 mole. Therefore, you would need 3.5 moles of oxygen to burn 1 mole of ethane at standard conditions.

How many moles of C2H6 are in 124 grams?
124 grams of ethane is equal to 4,124 moles.
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 molecules of ethane are present in 0.334g of C2 H6?
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
How many moles of carbon dioxide can be produced from 1.00 mole of ethane?
7/2O2+C2H6->2CO2+3H2O Mole ratio of C2H6:CO2=1:2 No.of mole of CO2=2mol
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
