a mol is a unit used to define the NUMBER of atoms of a given (pure) substance, and the weight of that number of molecules varies from substance to substance. The volume of a substance can vary greatly depending on the factors pressure and temperature, even though one may know exactly how many molecules there are being measured (1mol ~ 2.22X10^23 molecules or atoms). So with water, we have 2H's and 1O, so the molecular weight is 2X1.00794 + 1X15.9994=18.01528 grams per mole. This is a good thing to know, and with this you can calculate the VOLUME of H2O (which is really what you're looking for) provided that you know the PRESSURE and TEMPERATURE that the water is under/at. You haven't given either the pressure or temperature in your question, but I may be able to help you anyway: at STP (standard temp and pres), which is 20 degrees celsius and 1 atmosphere (atm) LIQUID H20 has a density of 0.9982 grams/cubic cm. For GASEOUS H2O, the density is 5.880X10^-4 grams/cubic cm at 100 degrees celsius and the specific VOLUME= 1701cubic cm/gram. This volume will not be the same however if the pressure and/or temperature is greater or lower. BUT, with the equation PV=nRT (P=pressure (in atm), T=temp in Kelvin, which is degrees celsius+273.15, R='rate', which is 8.314, and V= volume in meters cubed, and n= moles of gas. Using the temperature and pressure of the water, along with what you already know, you should be able to solve your problem. Just remember to do the right unit conversions! I hope this has been useful, and good luck!

How many grams are required to have 0.100 mol of C2H5OH?

2.430g. That's one tenth the number of grams in one mole of Mg, which would be 24.30, which is also its atomic weight. No, that is not a coincidence. Atomic weight of an element is always equal to the number of grams of an element in a mole of the same element.

How much Na is needed to produce a 5 grams of table salt?

5 grams of table salt is 5 grams of NaCl. NaCl has a molar mass of 58.443 grams/mol, so 5 grams would be .0855 mol NaCl. In one mole of NaCl there is one mole of Na, so there would be .0855 mol Na, or 5.235 * 1022 atoms Na.


How many grams of MgO are produced when 40 grams of 02 react with Mg?

Using the balanced chemical equation: 2Mg + O2 -> 2MgO, we can see that 1 mol of O2 reacts with 2 moles of Mg to produce 2 moles of MgO. Calculate the moles of O2: 40g O2 / 32g/mol = 1.25 mol O2 From the equation, 1.25 mol O2 will produce 2.5 mol of MgO. Calculate the grams of MgO produced: 2.5 mol MgO * 40.3 g/mol = 100.75 grams MgO.
