Calculate the number of molecules given grams i.e how many molecules are there in 21.6 grams of CH4?
To calculate the number of molecules in 21.6 grams of CH4, you need to first determine the molar mass of CH4 (methane). The molar mass of CH4 is approximately 16 g/mol. Next, divide the given mass (21.6 g) by the molar mass to get the number of moles. Finally, use Avogadro's number (6.022 x 10^23 molecules/mol) to convert moles to molecules.
How many hydrogen atoms are in 1.25 grams of CH4?
1,25 grams of CH4 contain 0,156696.10e23 atoms.
How many methane molecules of Ch4 have a mass equal to 3.20 grams?
One mole is equal to 6.022 x 1023 of anything. In this case, we are looking for molecules. So 1 mole=6.022 x 1023 molecules. We have 2.3 moles, so we want to know how many molecules are there. 2.3 mol CH4 x 6.022x1023 molecules CH4 / mol CH4 = 1.38x1024 molecules of CH4
How many molecules of CH4 are in 2.52 mol of CH4?
Divide 2.52 by molecular mass 16.Then multiply by avagadro constant
How many molecules of H2O and CO2 can be made from 4 molecules of CH4 and excess O2?
The balanced equation for the combustion of CH4 is CH4 + 2O2 ==> CO2 + 2H2O4 molecules of CH4 will produce 4 molecules of CO2 and 8 molecules of H2O
How many moles of CH4 are in 200 grams of CH4?
200 g CH4 x 1 mole CH4/16 g = 12.5 moles CH4
How many grams of CO2 are formed for every gram of CH4 that combusts?
The balanced equation for combustion of CH4 is CH4 + 2O2 ==> CO2 + 2H2OThus, one mole CH4 produces 1 mole CO21 g CH4 x 1 mole CH4/16 g = 0.0625 moles CH40.0625 moles CH4 ==> 0.0625 moles CO20.0625 moles CO2 x 44 g CO2/mole = 2.75 g CO2Thus, the answer would be that 1 grams of CH4 will produce 2.75 grams of CO2 after complete combustion.
How many moles in 64 grams of CH4?
There are 0.75 moles in it.You have to devide 12 by molecular mass
How many moles 64 grams of ch4?
First, determine molar mass of CH4: C:12g/mol + 4x H:1g/mol= 16g/mol Then divide by the number of grams. 64g/(16g/mol)= 4 moles of CH4
How many molecules in 10 grams of methane?
Find out the percentage of hydrogen in the molar mass of methane. Molar mass of CH4: C = 1 * 12.01 g = 12.01 g H = 4 * 1.01 g = 4.04 g Total = 16.05 g 4.04 g/16.05 g * 100% = 25.171% 0.25171 * 20 g = 5.0342 g There are about 5.03 grams of hydrogen in 20 grams of methane gas.
How many molecules of methane is CH4?
It represent a one molecule.CH4 stands for Methane
How many grams of hydrogen are in 5.60 moles of methane?
There are 67.2 grams of hydrogen in 5.60 moles of methane. Methane (CH4) has one carbon atom and four hydrogen atoms, so the molar mass of CH4 is 16 grams/mol (carbon) + 4 grams/mol (hydrogen) = 20 grams/mol. In 5.60 moles of CH4, there are 5.60 moles x 4 mol of hydrogen/mol of CH4 = 22.4 moles of hydrogen. Finally, converting moles to grams, 22.4 moles x 1 gram/mol = 67.2 grams of hydrogen.
