I really need your help...... urgently....?

Question

can someone give me how to convert :

a) grams to mole
b) mole to molecules
c) mole to ideal gases

Answer 1

For grams to mole, you find the molar mass of whatever substance you're working with (add the atomic masses together--it's the number with the decimal on the periodic table), and then put the number of grams you have of the substance over the molar mass. That gives you the number of moles in the substance.

For moles to molecules, there are exactly 6.022 x 10^23 molecules of a substance per mole. That's Avogadro's number. Simply multiply the number of moles times Avogadro's number and you have the number of molecules.

For moles to ideal gases, there are 22.4 liters of an ideal gas at standard temperature and pressure per mole of gas. Multiply your number of moles by 22.4 and you'll have how many liters.

Answer 2

grams to a MOLE?? what kind of Mole? A star nose mole? A mole as in a spy? or mole as in the condiment from Mexico??

And to convert a mole to molecules, I guess you'd have to vaporize it or something and then that would turn it into gasses, whether it would be an IDEAL gas is anyones guess.

Answer 3

A) grams to moles: divide the grams by the molar (molecular) mass

B) moles to molecules: multiply moles by 6.022 x 10^23

C) if it is at STP (standard temperature and pressure--1 atm and 273 Kelvin) then multiply moles by 22.6 L to get volume of gas

If you need something else with ideal gases, use PV=nRT, where P is pressure in atm, V is volume in L, n is number of moles of gas, R is the ideal gas constant .08206 L atm/mol K and T is temperature in Kelvins.

Hope this helps

Answer 4

a)1 gram molecular weight of a substance =1 mole
1 gram molecular weight os SO2=64 g=i mole
like tht 1 gram molecular weight of CO2=44g=1mole
b)mole is the amount of substance having avogadro's no. of particles.
molecules are the particles.
1 mole of any substance has molecules=avogadro's no.
c)ideal gas is the substance and mole is the amount of materials present in the substance

Answer 5

grams to mole = MULTIPLY BY 2.2

mole to molecules = MULTIPLY BY 1392.75

mole to ideal gases = EAT LOTS OF ONIONS

Answer 6

to convert grams to moles you need stuff density
moles are molecules
to get an ideal gas you still need its density(they are of different kinds with different preassures)

Answer 7

grams to mole
since each mole of compund/elements is different ill use H2Owater)
given 18g of water we would see that
O is 16g and H is 1g*2=2g
16g+2g=18g/mole
18g*1mole H2O/18g so 18g H2O=1mole

1molecule= 6.022*10^23

c)??? i have not yet encountered it

Answer 8

i will convert you to a mole

Answer 9

a) Well grams to moles is grams divided by the atomic weight equals moles.

b) moles x 6.022 x 10^23 gives you molecules

c) Dunno.
