A cube made of platinum (Pt)has an edge length of 1.00 cm. The density of Pt is 21.45 Part 1 of 2 Calculate the number of Pt atoms in the cube. Be sure your answer has the correct number of significant digits. Part 2 of 2 22 6.62 x 10 ris cm of significant digits. Pt atoms D 10 X Atoms are spherical in shape. Therefore, the Pt atoms in the cube cannot fill all the available space. If only 74.0 percent of the space inside the cube is taken up by Pt atoms, calculate the radius in picometers of a Pt atom. The mass of a single Pt. com is 3.240 x 10 g. [The volume of a sphere of radius -22 4 3. The volume of a cube is 13, where I is the length of a side. Avogadro's number is 6.022 × 10²³ .] Be sure your answer has the correct number S
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.
