How big is wake island?
Wake island is only 4. 063 square miles. It is halfway between Midway island and Guam. It is an atoll consisting of the three islets: WIlkos, Peale, and Wake.
What is the difference between volcanic bombs cinders and ash?
Vocanic dust is Fine vocanic ash that is under .063 millimeters. Vocanic ash is tiny parts of rock or glass, its size is under 2 millimeters. Volcanic bombs are magma that bursts out of the volcano and harden in the air. There size is over 64 millimeters. Vocanic cinders are dark glassy fragments that are produced by gas in the vocano.
What is the molarity of a solution that contains 5 moles of solute in 2 liters of solution?
* First! Figure out what pyridine's formula is: C5H5N So, we know that each molecule of pyridine has 5 C, 5 H, and 1 N. The cool thing about the formula is it doesn't matter what the unit is, as long as the ratio between the C, H, and N remains the same, BUT, being that we're doing chemistry let's use moles. :) 5 moles of C + 5 moles of H + 1 mole of N -->1 mole of C5H5N This can be a weird concept, because you might think "how do you put in 11 moles of stuff and get only one mole of product"... but, just like baking, you put in 5 cups of sugar, 5 cups of flour, and 1 cup of butter, but get one really big cookie (didn't say it would be a good cookie). Well, you put in a few moles of this, a few moles of that...and you get a single mole of C5H5N. * After you figure out the chemical formula, calculate molecular mass: 5 moles of carbon = 5 x 12.011 grams per mole = 60.055 grams 5 moles of hyrdrogen = 5 x 1.008 grams per mole= 5.04 grams 1 mole of nitrogen = 1 x 14.007 grams per mole= 14.007 grams ADD: 60.055 + 5.04 + 14.007 = 79.102 grams per 1 mole of C5H5N * Convert solute to moles! Now, we've figured out that 1 mole of C5H5N has a mass of 79.102 grams....but, we're only putting 5 grams in the solution. How many moles is 5 grams if 1 mole is 79.102 grams? Calculate: 5 grams/ 79.102 grams = .063 moles * Convert to moles per liter (not moles to part of a liter)! So...we are adding .063 moles to .5 liters of solvent, but, molarity is always expressed in moles per liter, so we have to convert this: (.063 moles C5H5N/.5 liter) x 1 liter = .126 moles C5H5N So, if .063 moles of C5H5N dissolved in .5 liters gives a solution of the same concentration as 1.26 moles of C5H5N dissolved in 1 liter (note - we now have it in moles per liter!). As molarity is moles per liter...and adding 5 grams of pyridine (which is .063 moles) to .5 liters of solvent produces a solution of the same concentration (molarity) as dissolving 1.26 moles of solvent in 1 liter, we have produced a 1.26 molar solution.
How many kilograms in 86.3 grams?
Remember K H D | d c m (kilo, hecto, deka, (liter, meter, gram), deci, centi, milli). These are the denominations you need to list when converting metric units. Kilograms are three places to the left of grams. So you have to move the decimal place three times to the left (same as dividing by 1000). You will get 83 g = .083 kg.
What is an ash-cinder volcano?
ash and cinder volcanoes have steep sides but arent very tall.when they erupt,small solid fragments of rock and ash come oyt of the volcanoe composite cone volcanoes are the most commmon. they are very tall,and they erupt with runny lava followed by explosive thick lava.

What is the mass in grams of 1.50 x 10 23 atoms Mg?
average atomic mass of magnesium is 24.3 g/mole so 24.3 X 1.56 X1021 / 6.02 X1023 = .063 grams
