73 gram of HCl was filluted by adding 144gram of water.how many gram atom of hydrogen are present in the dilute acid?

Answers

Answer 1

Mass of Hydrogen atoms : 18 g

Further explanation

Given

73 gram of HCl

144gram of H₂O

Required

Mass (gram) atom of Hydrogen

Solution

H atoms are in 2 compounds, H₂O and HCl, so we calculate their mass in each compound

mass H in H₂O :

[tex]\tt \dfrac{1}{36.5}\times 73=2~g[/tex]

mass H in HCl :

[tex]\tt \dfrac{2}{18}\times 144=16~g[/tex]

total mass = 2 g+ 16 g = 18 g

Explanation:

After burning your candle for a few hours you and your friend notice that it's mass has decreased. Your friend claims that the mass "disappeared". Why do you know he is wrong (Hint: it's a Scientific Law)? What actually happened to the mass? What form is that mass in now? What is this process called?

Answers

Answer:

The law of conversion of mass is a scientific law that says that mass or matter can not be created or destroyed like energy but changes its form in a different type of state. So, by the law of conversion of mass, you can say that mass is not disappeared but change in different forms of states of matter like gas, soot, or melted residues of candle and ash of thread.

Due to this, the mass of the solid or waxy state due to burning changes to gas released by burning and residue of wax that will be equal to the mass of the original mass.
