1. a sulfur-32 atom contains 16 protons, 16 neutrons, and 16 electrons. what is the mass (in grams) of a sulfur-32 atom?
The mass in grams of a sulfur-32 atom is 32.
That is how the isotopes are identified, showing the mass number of the isotope, which is the sum of protons and neutrons: 16 protons + 16 neutrons = 32 mass number = mass in grams of the isotope.
2. the mass of a neutron is 1.67 x 10-24 g. approximately what number of neutrons would equal a mass of one gram?
divide 1 gram by the number of neutrons per gram:
number of neutrons = 1 g / 1.67 * 10 ^ - 24 g / neutrons = 0.5998 * 10 ^ 24 neutrons = 5.998 * 10 ^23 neutrons.
Explanation:
miscible liquids: water and alcohol
immiscible liquids: water and oil
Answer:
Table salt is considered to be a compound because it is made up of two elements (sodium and chloride,) while sodium itself is a raw element. That's why table salt is considered to be a compound, while sodium is not.
Hope this helped, have a nice day! :)
