What is the molecular weight (mass) for KOH? <br><br> 56.10 g/mol <br> 57.00 g/mol <br> 28.00 g/mol
IRINA_888 [86]

Molecular weight (mass):

It is the molecular mass of a substance that can be calculated by sum of atomic weight of atoms that are present in the molecule multiple by the total number of molecule.

In KOH,

Atomic weight of K=39.1

Atomic weight of O=15.9

Atomic weight of H=1

Molecular weight=Atomic weight of K+Atomic weight of O+Atomic weight of H

=56.1 g/mol

So the answer is A that is 56.10 g/mol

sergeinik [125]

Answer:

             70.15 cm³

Solution:

Data Given;

                  Mass  =  55 g

                  Density  =  0.784 g.cm⁻³

Required:

                  Volume  =  ?

Formula Used:

                  Density  =  Mass ÷ Volume

Solving for Volume,

                  Volume  =  Mass ÷ Density

Putting values,

                  Volume  =  55 g ÷ 0.784 g.cm⁻³

                  Volume = 70.15 cm³
