How many grams are in 2 moles of h2o?

36.03056 grams hope this hlps

               m = 36 g

Explanation:

                The formula of mole is given as,

                           n = m / M      (1)

Given data:

                          n = 2 mol

                          M = 18 g/mol

                          m = ?

Solution:

            Solving equation (1) for m,

                       m = n × M

            Putting values

                       m = 2 mol × 18 g/mol

                        m = 36 g

solute : a solute is a substance that is dissolved in another substance is known as a solvent. it is mixed with a special mixture know as homogeneous mixture.

solvent: a solvent is a substance that dissolved a solute, which results in a solution is known as solvent.

your answer is a. the enthalpy of formation for a pure element in its standard state is always positive.
