This cannot be answered because it is essential to know what element you're dealing with here. 44.3 grams of iron will contain considerably less atoms than 44.3 of hydrogen. Therefore, the number of moles in 44.3 grams of iron will differ from the number of moles in 44.3 grams of hydrogen.
Find the formula weight of the material and multiply by the number of moles:
44.3 mole x FW gram/mole = ____ gram
...for hydrogen gas (H2) the formula weight is 1.00797 g/mol x 2 = 2.01594 g/mol.
44.3 mol x 2.01594 g/mol = 89.3 g
16 grams of oxygen how many moles is 0,5 moles.
85.636 grams carbon (1 mole C/12.01 grams) = 7.1304 moles of carbon ---------------------------------
moles = weight in grams / molecular weight = 56 / 28 = 2 moles
26,2 grams Ta is equal to 0,145 moles.
120 grams of calcium contain 2,994 moles.
To calculate the mass in grams of 2.5 mol of manganese (Mn), you need to multiply the number of moles by the molar mass of manganese. The molar mass of manganese is approximately 54.94 g/mol. So, 2.5 mol of Mn would be 2.5 mol x 54.94 g/mol = 137.35 grams.
454 grams per lb. 20/454=.044 20gms=.044 lbs.
A mole weighs 58 grams
16 grams of oxygen how many moles is 0,5 moles.
The molar mass of gold is approximately 197 grams/mol. To convert moles to grams, you multiply the number of moles by the molar mass. Therefore, 2.8 moles of gold would be approximately 2.8 * 197 = 551.6 grams.
85.636 grams carbon (1 mole C/12.01 grams) = 7.1304 moles of carbon ---------------------------------
The clarity of this question is not clear. I will assume grams and possibly moles as that number does not look like a number of atoms. Grams first, then moles. 4.0 X 102 grams quinine (1 moleC20H2N2O2/302.236 grams)(2 moles N/1 mole C20H2N2O2) = 2.6 moles nitrogen =============== Pretty much the same procedure if you meant moles just no dividing out a mass.
See the Related Questions to the left of this answer:"How do you convert from grams to moles and also from moles to grams?"
53 grams ÷ 18.01 grams/mole = 2.94 moles
1 mole is equal to 18 grams of H2O, so 60 grams is 3.33 moles.
moles = weight in grams / molecular weight = 56 / 28 = 2 moles
all you have to do to fine the moles of any element is divide the given grams by the molar mass (which you can find on a periodic table of elements) Likewise, if you need to find the grams, just multiply the number of moles by molar mass. moles = grams/molar mass grams = moles x molar mass your equation should look like this: moles = 89.0 / 17.0 moles = .471
