9.31 g has the same mass as what?
If you go to kitco.com and see that gold is at $1000 a troy oz, Get a calculator and divide $1000 by 31.1035 (*how many grams there are in a troy ounce) It will show that gold nuggets weighing 2 gms. would be worth $32.15x2=$64.30 Right now they are worth: $906.10 divided by 31.1035 = $29.13x2 =$58.26
You don't need moles to solve stoichiometry problems. What you do need to do is to turn things (amounts) into the same nomenclature. If you want to turn grams into liters you need to go through several steps to get from grams to liters. For example if you have 20 grams of a substance and the atomic weight (from the periodic table) of one molecule of the substance is 40 grams, you need to convert to milligrams. 40 grams = 40,000 mg (1gm=1000mg). So divide 40,000mg by 40 gm. 20gm = 40,000 mg / 40 mg. The grams cancel each other out and you're left with 20 x 40,000 mg / 40. Now you need to get rid of the milligrams. 1 mg = 1 ml so continue with your problem by dividing 40,000 ml by 40,000 mg. Now the mg's cancel each other out and you have 20 x 40,000 x 40,000 ml divided by 40 x 40,000. Now turn ml into liters. 1000 ml = 1 liter so add to your equation 40,000 ml = 10 liters. The ml cancel each other out and you have: 20 x 40,000 x 40,000 x 10 divided by 40 x 40,000 x 40,000. The two 40,000's on top cancel out the two 40,000's on the bottom so you have 20 x 10 divided by 40 which = 200 divided by 40 which equals 5 liters. Divide by 5 and you get 1 liter. The trick is to draw a long line and put the multipliers on top and the divisors below with up and down lines between the sections. If there is something on top that is also on the bottom, they cancel each other out. That can be numbers or units of measurements. This method allows you to convert almost anything to anything else. All you have to know are the conversion numbers (like how many killograms = 1 pound). As you can see, you can even go from metric to US numbers and from solids to liquids. Good luck!
0.120 g
7g = 7000 mg
You did go to school, right? 7 grams is equal to 7000 milligrams.
4 g = 4000 mg
The prefix "milli" means 1/1000. Therefore, one gram has 1000 milligram.
1 gram = 1000 milligrams. You now have all the information required to work out, for yourself, the answer to this and similar questions.
This is not a valid conversion; milligrams (mg) and grams (g) are measures of weight or mass and mL (milliliters) is a measure of volume.
10,000 milligrams go into 1 kilogram.
1 gram = 1000 milligrams, so 500 mg = 0.5 grams, so 5 / 0.5 = 10 times

Two. There are 1000 milligrams in one gram.
1 kilogram = 1 000 000 milligrams therefore, 2 kilograms = 2 000 000 milligrams
