Calculate the mass of 0.5mols of CH3COOH​

I) Acetic acid (CH3COOH) ii) Ethanol (C2H5OH) iii) Carbon dioxide
b) Calculate the mass of the following :
i) 0.5 mole of N2 gas(mass from mole of molecule)
ii) 0.5 mole of N atoms ( mass from mole of atom)
iii) 3.011 × 1023 number of N atoms(mass from number)
iv) 6.022 × 1023 number of N2 molecules (mass from number )
c) Calculate the number of particles in each of the following :
i) 46 g of Na atoms (number from mass)
ii) 8 g of O2 molecules ( number of molecules from mass)
iii) 0. 1 mole of carbon atoms ( number from given moles)
