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: I can cofirm that it is C.

Step-by-step explanation:

Answer 2

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
