What is total no of electrons present in 1 mole of methane?

There are 10 moles of electrons.

How do you find moles of electrons?

Converting coulombs to moles of electrons, moles of electrons = coulombs / F = 6.673 x 102 / 96487 = 6.916 x 10-3 mol. from which, one mole of H2 formed requires two moles of electrons.

How many Faradays are in 1 mole of electrons?

96,485 coulombs
96,485 coulombs = 1 Faraday. 1 Faraday = 1 mole of electrons.

How much is 1 mole of Na2O in grams?

The answer is 0.016134512787731. We assume you are converting between moles Na2O and gram. You can view more details on each measurement unit: molecular weight of Na2O or grams. This compound is also known as Sodium Oxide. The SI base unit for amount of substance is the mole. 1 mole is equal to 1 moles Na2O, or 61.97894 grams.

How do you calculate the number of Na+ ions in Na2SO4?

Use the number of moles of sodium per mole of sodium sulfate. First, calculate the moles of sodium sulfate you have in a 14.2g sample. Now, for every 1 mol of N a2SO4 you have 2 moles of N a+ ions.

How many ions are present at two Na^+ ions and one O^-2 ion?

The formula says there are 2 Na atoms and 1 O atom. Looking at the periodic table, Na is a metal in group 1 and therefore has a + 1 charge. O is a non- metal in Group 6 and therefore has a -2 charge. So the ions present at two Na^+ ions and one O ^-2 ion.

How do you find the molar mass of sodium sulfate?

Find the molar mass of sodium sulfate. molar mass = atomic mass in grams. 2(23) + 32 + 4(16) = 142 grams per mole. Divide the mass of the sample by the molar mass to obtain moles.
