1 mole of NaCI = Mass of Na 23 , Mass of C 12, Mass of I 127 = 23 + 12 + 127 = 162g therefore :
if 162g = 1 mole
16g = ?
1 x 16/ 162 = 0.098
This depends on the mass of NaCl.
As one mole of CO2 contain 2 oxygen having molar mass 32. Soo there will be 0.50 moles of CO2 which contain 16g of oxygen....!
Divide that number by Avogadro's number: 3.968x10(23) / 6.02x10(23) = 0.659mol Mg, which would be about 16g.
There are 6.023x10^23 molecules in one mole of a compound. So now, you have to find how many moles of each compound you have. CO's molecular weight is (12+16) = 28 g/mol N2's molecular weight is (14+14) = 28 g/mol So you find the moles of each. moles of N2 = 20g/ 28g/mol = .714 moles moles of CO = 16g / 28 g/mol = .571 moles So, N2 has (.714 *6.023x10^23) has 4.3 x10^23 molecules and CO (.571 *6.023x10^23) has 3.4x10^23 molecules. So, 20g of N2 has more molecules than 16g of CO
using the formula: n=m/gfm no. of moles=mass/gfm you take the gram formula mass (gfm) as 4. and given the mass is 16g, both numbers can be substituted into the formula... n=16/4 = 4 the number of moles present in 16g of helium is 4 moles.
This depends on the mass of NaCl.
He = helium 16 grams He (1 mole He/4.003 grams) = 3.99 moles He You can call it 4.0 moles He
There are two moles of sodium ions in two moles of sodium chloride.
As one mole of CO2 contain 2 oxygen having molar mass 32. Soo there will be 0.50 moles of CO2 which contain 16g of oxygen....!
It depends on how many moles you would like. 0.2M is a ratio which states that you have 0.2 moles per liter of solution.
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
Divide that number by Avogadro's number: 3.968x10(23) / 6.02x10(23) = 0.659mol Mg, which would be about 16g.
Divide by molar mass of NaCl (not NaCI ! ) which is 58.44 g/mol NaCl.

There are 0.75 moles in it.You have to devide 12 by molecular mass
No. of atoms in NaCI are 3. No. of atoms in 36 NaCI are 36*3=108 But no NACI like compound exist.
