number of moles present = molar mass (g)
1 mol
The molar mass is the sum of the atomic masses present in a compound. Be sure to take quantity into acount.
For intance...
the molar mass of H2O is 18.02 because 1.01+1.01+16=18.02

∙ 11y agomoles divided by grams gives the inverse of molecular weight, which i have never come across.
number of moles = mass / molecular mass. molecular mass is grams per mole

∙ 13y agoMultiply the number of moles by the relative molecular mass.
mass of 2 moles of water
= 2 mol x 18.0 g/mol
= 36 g

How many liters of water can be made from 34 grams of oxygen gas and 6.0 grams of hydrogen gas at STP?
At STP1mol O2 = 22.4L1mol O2 = 6.022 x 1023 molecules O222.4L O2 = 6.022 x 1023 molecules O2Convert liters O2 to moles O23.36L O2 X (6.022 x 1023 molecules O2/22.4L O2) = 9.03 x 1022 molecules O2
What is 1000 millimoles in milligrams?
You haven't stated the compound or molecular weight. The formula you need is the number of moles = mass / molecular mass. If you have millimoles, multiplying by molecular weight will convert to milligrams.
How many moles of K2SO4 are in 15.0 grams of K2SO4?
Multiple the moles of K2SO4 by the molecular weight of 174.2592 grams. That should equal 210.85 grams.
How many grams are in 200 grams?
There are 200 grams in 200 grams.
How many grams is 27 grams of cannabis?
About 907.2 grams.
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.
Why divide glucose mgs by 180 for millimoles?
Because the formula for calculating moles is dividing grams by the molecular weight. The molecular weight for glucose is 180. grams to moles is also the same as milligrams to millimoles.
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
What is the mass in kilograms of 3.25 millimoles of water?
The molecular weight of water is 18g/mol. There are 0.00325 moles in 3.25 millimoles. 0.00325*18 is 0.0585 grams. This is 0.0000585 kilograms.
How many grams of C6H12O6 are need to produce 8.57 millimoles?
Mol wt of C6H12O6 = 6*12 + 1*12 + 16*6 = 72+12+96 = 180 This implies that 180 grams of the compound is equivalent to 1 mole 1 mole = 180 grams => 1 millimole = 180 milligrams => 8.57 millimoles = 180*8.57= 1542.6 milligrams = 1.5426 grams

How do you calculate millimoles?
Millimoles are a unit of measurement based of mole, which measures the amount of substance in something that has an equal number of atoms and elementary entities. Millimoles are calculated by multiplying the amount of moles by 1,000.
How do you convert 2.55 millimoles to moles?
You need to divide by 1000 here. This is because there are 1000 millimoles in a mole. 2.55/1000 gives you 0.00255 moles.
