For this you need the atomic (molecular) mass of C3H4. Take the number of grams and divide it by the Atomic Mass. Multiply by one mole for units to cancel. C3H4=40.0 grams
10.0 grams C3H4 / 40.0 grams = .250 moles C3H4

How do you solve for how many grams are in 2.38 moles of calcium carbonate?
No. of moles=wt. of substance/molecular wt. hence, wt. of substance= 2.38*100=238
How many moles of water are there in 1.792 L?
95,474 moles
How do you prepare 5mM EDTA of 100ml solution?
5mM = 0.005 moles 100 mL = 0.1 Liters Molarity = moles of solute/Liters of solution 0.005 M EDTA = X moles/0.1 Liters = 0.0005 moles EDTA =_____________ Now, look up the molecular formula for EDTA and find how many grams needed to add to your 100 mL.
How many moles of carbon are present in a 100g sample?
moles = mass (g) divided by the molecular weight (g/mol) moles = 100g/12.01
How many moles is 3 grams of carbon?
By definition, one mole would be the same as the atomic mass. You take the number of moles and multiply it by the atomic mass. So if you have just 1 mole, the number of grams will be the atomic mass. Carbon's atomic mass is 12.011 grams.
5.8 grams in 1 liter of water equals how many moles?
if you have 100 liters how many moles does that equal?
How many moles of phosphorus atoms are in 100 grams of P4S10?
4.00
What is the number of moles in 100 g MgCO3?
100 grams MgCO3 (1mol MgCO3/84.32g) = 1.19 moles of MgCO3
100 grams of ammonia equals how many moles?
For this you need the atomic (molecular) mass of NH3. Take the number of moles and multiply it by the atomic mass. Divide by one mole for units to cancel. NH3=16.0 grams100 grams NH3 / (16.0 grams) = 6.25 moles NH3
How do you solve for how many grams are in 2.38 moles of calcium carbonate?
No. of moles=wt. of substance/molecular wt. hence, wt. of substance= 2.38*100=238
How many moles Fe are in a sample of Fe2O3 that contains 100g O?
100 grams oxygen (1 mole O/16 grams)(2 mole Fe/3 mole O) = 4.17 moles iron --------------------------
What is the mass of 100 millimoles of caffenine C8H10N4O2?
100 millimoles is 0.1 moles. To convert moles to grams, you need to multiply by the molecular weight, in this case, 194.22g/mol. 0.1*194.22 is 19.422 grams.
How many atoms does 100 grams of gold have?
Gold has a molar mass of 196.96655 grams per mole. 100 grams then is equal to .508 moles which makes 3.059 E23 atoms of gold.
