1. Count The Number of Each Atom The first step to finding the molar mass of Gold is to count the number of each atom present in a single molecule using the chemical formula, Au: ElementNumber of Atoms Au (Gold) 1 2. Find Atomic Mass of Each Element Next, using the periodic table,...
Despite the extremely light weight of an atom, it is quite possible to convert the mass of a single atom into grams based on the mass of a single atomic mass unit or AMU. The mass of an AMU is 1.661 X 10-24 grams.Answer and Explanation: The mass of 4 atoms of copper in grams is...
If the atomic mass of an element is x, what is the mass in grams of 6.02 X 10^{23} atoms of the element? What is the mass in kilograms of a single atom of carbon? What is the average mass of a single silicon atom in grams? What is the mass number of the uranium-238 atom?
Density, mass per unit volume of a substance. The formula for density is d=M/V, where d is density, M is mass, and V is volume. Density is commonly expressed in units of gram per cubic centimeter. For example, the density of water is 1 gram per cubic cen
