Best Answer: 1. find the length of a mole(animal) eg..2meters and multiply by 6.02*10^23. then divide that
distance by the distance from here to pluto

comprehend, so think of it like a really big dozen. For answer 1, you need to know how long the average mole (animal) is, and how far it is to Pluto. Say they're 6". So just multiply that out and you'll have your distance. For 2, you need the weight of the hope diamond. The weight of a mole of carbon atoms is 12 grams--carbon is the

standard on which the mole is based. I wouldn't answer #3, because it's based on a false assumption that the ocean weighs what standard water does-there's the matter of salt in there, and if you wanted extra credit you could factor in salinity and the weight of the salt. A lot of chemistry is making sure your units cancel and equations are balanced. You shouldn't have much of a problem if you're careful.

It is very simple You are probably familiar with a dozen. In a dozen there could be 12 cows, 12 oranges or 12 anything. A mol is similar to the dozen concept. If you have a mol of something, it means you have 6.02x10^23 of anything. This quantity 6.02etc is know as the avogadro number. So lets look at your third question: 1 mole water is 18 grams. Find the total volume of water in the ocean and multiply by the density, say x So if 1 mole is 18 g then N mole will be x g x = 18 * N / 1

One mole of anything is Avogadro's number of those things - 6.02 * 10^23. So, for the first question you would need to find the distance to Pluto and the average length of a mole (the animal). For the second question you would need the weight of the Hope diamond, then look on the periodic table to find the atomic weight of carbon (diamonds are pure carbon). For the third question you would need to find out how much water is in the Atlantic ocean. Geoffrey S · 1 decade ago 0

Nothing to do with Avogadro. A mole is a quantity (in grams) that equals the molecular number of the substance. Oxygen has atomic number 16, hydrogen 1, so H2O = 2*1+16=18. So indeed a mole of water is 18grams. The mole (animal) is something like a rat. The qustions (1, 2, 3) you have are rather like quizes, they don't really have answers. They are there in order to show you the different meanings of the word mole. cpinatsi · 1 decade ago 0

First you got to find out how much the Hope Diamond weighs in grams 45.52 carats equals 9.104 grams (that is the weight of the diamond by itself. Now we can convert 9.104 grams to moles 12.011 grams equals 1 mole 9.104/12.011 = .758 Moles of carbon A mole equals 6.0221415 × 10^23 atoms multiply that by .758 that will give you how many carbon atoms are in the hope diamond Endotech · 1 decade ago 0

1 mole = 6.02 x 10^23 atoms or molecules of a substance or 1 mole = the molecular weight (or atomic weight) of a substance ion grams or 1 mole = 22.4 liters of any gas at STP. question 2 is probally the easiest to solve..Find the weight of the Hope Diamond in grams and then divide by 12 (the atomic weight of carbon) to find the number of moles.

Q1...1 mole of moles requires Avagadro's number (6.02 x 10^23). If you had this many moles, you need to multiply it by the length of a mole and this will give you the length of 1 mole of moles. If you know how many inches to pluto, divide the length of the mole of moles by the distance to pluto (make sure the units are the same) and it will tell you how many times it will reach to pluto and back. Q2...you need to know the mass of the hope diamond in grams. Then you divide the mass of the diamond by the atomic mass of carbon (12.001g/mol) and you will be left with the moles of carbon in the hope diamond. This is all assuming the diamond is 100% carbon. If not, take the percentage of carbon times the mass of the hope diamond and run that result through the above calculation. Q3...You will need to know the percent water in the entire Atlantic. Multiply that by the mass of all the water in the Atlantic (in grams) and then divide that by 18 g/mol (molecular mass of water) and you are left with moles of water in the Atlantic. imsurroundedbyidiots · 1 decade ago 0
