Calculate the mass of hydrazine (N,H,) that contains a million (1.00 × 10°) hydrogen atoms. Be sure your answer has a unit symbol if necessary, and round it to 3 significant digits.
States of Matter
The substance that constitutes everything in the universe is known as matter. Matter comprises atoms which in turn are composed of electrons, protons, and neutrons. Different atoms combine together to give rise to molecules that act as a foundation for all kinds of substances. There are five states of matter based on their energies of attraction, namely solid, liquid, gases, plasma, and BEC (Bose-Einstein condensates).
Chemical Reactions and Equations
When a chemical species is transformed into another chemical species it is said to have undergone a chemical reaction. It consists of breaking existing bonds and forming new bonds by changing the position of electrons. These reactions are best explained using a chemical equation.
According to question
4 atoms of H are in 1 molecule of N2H4
Hence, 1.00×10⁶ atoms are in = 1/4× 1.00×10⁶ molecule
= 2.50× 10⁵ molecules of N2H4
Now, mass of N2H4 = no.of molecules/avagadro no. × molar mass
= 2.50×10⁶/6.022×10²³ × 32.0452
= 1.33×10-¹⁷ gram
