What is the mass, in grams, of 1.11 mol of water, H2O?

Explanation:

To find the mass of 1.11 mol of H2O we must first find it's molecular mass after that we use the formula

where

m is the mass

M is the molecular mass

n is the number of moles

From the question

n = 1.11 mol

Taking

M( H) = 1 g/mol , M(O) = 16 g/mol

We have

M( H2O) = 2 + 16 = 18 g/mol

So we have

m = 1.11 × 18

We have the final answer as

Hope this helps you

the mass of the cathode increases because ions from the solution get reduced to atoms and become part of the cathode.
