SECTION 2: WHY DOES A MOLE HAVE A DIFFERENT MASS? PART A: WATCH THE VIDEO to fill in the blanks and answer the questions. Label the following diagram: Carbon The is at the center of an atom. This is where we find the but we also find the 12.0107 Subatomic particles have very very small mass. So small, that it's inconvenient to use normal mass units like g or kg. Instead, chemists derived a new unit called the The mass of an atom, or in other words its just comes down to the number of protons and neutrons since they both have a mass of 1 amu.

Archeologists discover a gold crown in an ancient tomb. When they place the crown in a tub of water it displaces 941.2 mL of water. The density of gold is 19.3 g/mL.Gold is worth $57,056.24 per kg (or was on the day this question was written). Without taking into consideration any historical value for the crown, what is the crown worth?

2 What methods are used to sep X G In Part Il of experiment 5, a 1:1: X + u/ultra/courses/_393452_1/cl/outline * Question Completion Status: QUESTION 3 After you complete the second step, you will be left with a clear colorless liquid. What should be done to the liquid to finish the separation? O Heat the mixture to evaporate the liquid O Add a base to neutralize the solution. O Nothing - you are done since you have a pure, clear, colorless substance O Add the residue back to the solution and dry. QUESTION 4 In Part II of experiment 5, a 1:1:1 mixture of sand, salt, and salicylic acid must be separated. Order the following steps necessary to separate this mixture into three pure, dry solids. Filter the liquid leaving a filtrate with just salt dissolved and a residue of sand. v Add hot water to the residue obtained in two steps prior to this one.

Which statement is FALSE? O A pure substance can be varied by changing the proportion of pure substances making it up A mixture can be separated into 2 or more substances by physical or mechanical means A pure substance had properties that are constant, no matter where you find it A pure substance has constant chemical composition A mixture's composition can be varied by changing the proportion of pure substances making it up
There are 2 boxes for each reactant and product. Type the coefficient in the first box and the chemical formula in the second. Enter the chemical formulas in the order they appear in the problem. Each box must have a coefficient or formula. Type in a "1" if you did not change the coefficient. Type the formula in this format: CO_2. Omit the subscript "1" in the chemical formulas. This is case-sensitive. Carbon monoxide reacts with iron(III) oxide to produce iron and carbon dioxide.
Percentage Abundance. The element rubidium consists of two isotopes, one having an isotopic mass of 84.912 and the other having an isotopic mass of 86.920. Determine the percentage abundance of the lighter isotope. Record the answer to the correct number of significant figures. Show the numerical set-ups. Include units and the correct number of significant figures in the set-up.
A piece of copper has a volume of 560 L what is mass of sample in grams. For the problem it gives me 1cm^3Cu = 9g CU 9.5 x 10^21 atoms Cu= 1 Cu 1KG =1000g 1cm^3 =1mL 1L=1000cm^3 It basically wants me to write out the conversions correctly i just dont know which ones to use. Thank you so much for the help I really appreciate it.
