Given: 2.0 mol of methanol, molar mass of methanol(32.0 g/mol)
Wanted: Grams of 2.0 mol of methanol

Grams of solute= 2.0mol * 32.0g/1 mole = x

2.0 * 32.0 = [64.0g CH3OH]

Hope this is helpful!

Answer:

                 Mass  =  64 g

Solution:

             Mole is the quantity of a substance that contains number of particles exactly equal to particles found in 12 g of Carbon-12. The number of particles are 6.022 × 10²³ also called as Avogadro Number. Mole is given as,

                         Mole =  Mass / Molar Mass    ----- (1)

Data Given;

                  Mole  =  2.0 mol

                  M.Mass  =  32.0 g.mol⁻¹

                  Mass  =  ??

Solving equation 1 for Mass,

                  Mass  =  Mole × M.Mass

Putting values,

                  Mass  =  2.0 mol × 32.0 g.mol⁻¹

                 Mass  =  64 g
