Question

molarity of 1000ml of c2h5oh if density of it is 0.8gm/ml​

Answer 1

Answer:

Molarity is 17.4 M

Explanation:

molecular weight of C₂H₅OH =

Volume = 1000 mL = 1L

Density = 0.8 g/mL

Mass = Volume × Density = 1000 × 0.8 = 800 gm

Moles of C₂H₅OH = Weight/Molecular Weight

                              = 800/46

Molarity = Weight/Volume in L

Therefore, the molarity of given solution of C₂H₅OH

= 800/46

= 17.4

Hope this helps.
