Calculate the mass of tetraborane (B,H10) that contains a billion (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.
1 mol of B4H10 contains 10 moles of H atoms
Molar mass of B4H10 = 53.32g/mol
and, 1 mol = 6.022 × 1023 atoms
Thus, 53.32g of B4H10 contains 10 × 6.022 × 1023 atoms of H
