The formular you need is M = n/m (molar mass = amount of substance/mass), or n = m/M
Aluminium has a molar mass of 26.982 g/mol. The given mass is 3 grams. Therefore:
n(Al) = 3g / (26.982g/mol) = 0.11mol

How do you Convert 40.79 kilojoules per mole to joules per grams?
40.79 H2O kj/moles x 1 moles/18 grams= 2.266/1000=0.002266 joules/grams
Metric ton equals how many moles?
The average male mole weighs 115 grams and the average female 85 grams. If we assume that the population of moles is equally divided between males and females, then then the average weight of a mole is 100 grams. This is very easy to convert to tons, as there are 1000 grams in a kilogram, and 1000 kilograms in a ton. We can then say: (1000 kg * 1000 g/kg) / (100 g/mol) = 1000000 g / (100 g/mol) = 10000 mol So you would need about 10000 moles to get a mass of one metric ton. If you collect them in regions where they are densely packed, you'll usually find about 7 to 12 moles per hectare, which means that to collect enough moles to reach a mass of one ton, you'll need to hunt them to local extinction in an area of roughly 1000 hectares (about 2500 acres) in regions where they are most densely found.
How many grams of NaC1 are needed to make1.00 liter of a 3.00M NaC1 solution?
Molarity = moles of solute/volume of solution. 1 liter = 1000 millilitetrs 3.00M = X Moles/1000ml = 3000 millimoles, or 3 moles NaCl 3 moles NaCl (58.44g NaCl/1mol NaCl ) = 175.32 grams needed. About 4/10 of a pound of salt.
How many moles are in 300mg of aspirin?
Aspirins formula is C9H8O4 300 mg Aspirin (1 gram/1000 mg)(1 mole aspirin/180.154 grams) = 0.00167 moles aspirin
Calculate the number of moles in 0.525 g of AgCl.?
moles= mass/Mr so 525 divided by the Mr of ZnCl-2 Mr of ZnCl-2= (Ar of Zn= 65.37)+(2 x Ar of Cl= 2 x 35.5= 71) = 136.37 moles= 525/136.37 = 3.85 moles to 3 significant figures. (in grams) divide the answer by 1000 to get mg so 3.85/1000= 0.00385 moles
How do you Convert 40.79 kilojoules per mole to joules per grams?
40.79 H2O kj/moles x 1 moles/18 grams= 2.266/1000=0.002266 joules/grams
How do you convert 50 milli molar of sodium acetate into grams?
we know, 50 mM = 50/1000 moles per litre = 0.05 moles no. of moles = weight in grams/ weight of one mole weight of one mole of sodium acetate (CH3COONa) = 83g per mole no. of moles = 50/1000 = 0.05 moles thus weight in grams = 0.05*83 = 4.15 g
How many moles of water are there in 1000 grams of water?
Water has a molecuar mass of 18. This means it weights 18g per a mole. The molecular formula for water is H20. Your answer for how many moles in 1000 grams of water is 55.5084351.
Convert 125 grams of calcium to moles?
For this you need the atomic mass of Ca. Take the number of grams and divide it by the atomic mass. Multiply by one mole for units to cancel.125 grams Ca / (40.1 grams) = 3.12 moles Ca
If 1000 g of PCP are dissolved in 1000 L of water what is the concentration in terms of moles per liter?
The molar mass of PCP (phencyclidine) is 243.387 grams per mole. So 1000 g of PCP is equal to 4.108 moles. If that many moles is in 1000 liters, than the molarity (in moles per liter) is 4.108 ÷ 1000 = 0.0041 M
How many moles of sodium are in 5.13 kg of sodium?
Quite a few! 5.13 kilograms sodium (1000 grams/1 kg)(1 mole Na/22.99 grams) = 223 moles of sodium =================
How many moles are in 1.2 kilograms of calcium bromide?
1.2 Kilograms Calcium bromide (1000 grams/1 kilogram)(1 mole CaBr2/199.88 grams) = 6.0 moles calcium bromide
How do you calculate the number of moles in 4.637 grams in Mg?
For this you need the atomic mass of Mg. Take the number of grams and divide it by the atomic mass. Multiply by one mole for units to cancel.4.637 grams Mg / (24.3 grams) = .191 moles Mg

How do you calculate milligrams of caffeine in 60 mL sample?
You have to know the concentration first. That will either be in grams per milliliter (or milligrams per milliliter), or it could be in moles per liter (molarity). If it's given in grams per milliliter, just multiply that number by 60 and multiply by 1000.If it's given in moles per liter, than first find how many moles in 60 mL by multiplying by 0.06, and then convert moles to grams using the molar mass of caffeine (194.19 grams per mole).See the Related Questions for how to convert moles to grams.
