Mass of NaOH = 223.983 g
Further explanation
A mole is a unit of many particles (atoms, molecules, ions) where 1 mole is the number of particles contained in a substance that is the same amount as many atoms in 12 gr C-12
1 mole = 6.02.10²³ particles
While the number of moles can also be obtained by dividing the mass (in grams) by the molar mass of an element or molecule
[tex]\tt \boxed{\bold{n=\dfrac{mass}{MW}}}[/tex]
MW of NaOH = 39.997 g/mol
moles of NaOH= 5.6
Mass of NaOH :
[tex]\tt mass=mol\times MW\\\\mass=5.6~moles\times 39,997 g/mol\\\\mass=223.983~g[/tex]
