Question

Jayden has been given 5 cubic centimeters each of 4 unknown samples of gaseous substance. He has been asked to identity which one is hydrogen. Sample A 0.00036, Sample B 0.000018, sample C 0.00045, D 0.000022. If the density of hydrogen is 0.00009 g/cm^3, which of the unknown is hydrogen.

Answer 1

Answer:

             Sample-C is the hydrogen.

Solution:

            Data Given:

                                Volume  = 5 cm³

                                Mass of Sample-C  =  0.00045 g

                                Reference Density  =  0.00009 g/cm³

            Formula Used;

                                Density  =  Mass / Volume

                                Density  =  0.00045 g / 5 cm³

                                Density  =  0.00009 g/cm³
