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 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.
What is the conversion of 1250 millimoles to moles?
There are 1000 millimoles in a mole. So you need to divide by 1000 here. 1250 millimoles / 1000 is 1.25 moles.
How do you convert moles to milligrams of an element?
First off you multiply moles by 1000 to convert to millimoles. Next you multiply by the molecular weight (found as the bigger figure on the element on the periodic table).
How do you convert volume of 0.2mL of 0.5mM glycine to millimoles?
So molar means moles per litre. So you have to divide by 1000 and multiply by 0.2. 0.5/1000*0.2 is 0.001 millimoles of glycine in your 0.2 millilitres.
How many Cu atoms are their in3.7x103 millimole?
3.7x10^3 millimoles is 3.7 moles. To convert moles to atoms, multiply by avagadro's number. 3.7 x 6.022x10^23 is 2.22814x10^24 atoms.
A chemist adds 1.15 L of a .00335M copper II fluoride CuF2 to a reaction flask how many millimoles of copper II fluoride has the chemist added to the flask?
So first off, M means how many moles in every litre. So you have to multiply by the amount of litres. 0.00335 x 1.15 gives you 0.0038525 moles. Multiply by 1000 to convert to millimoles. This gives you 3.8525 millimoles.
How do you convert millimoles per liter to grams per milliliter?
First you divide by 1000 to convert to moles/litre. Then you find the molecular mass (add up atomic masses from the periodic table). Multiply moles per litre by the molecular mass and it is in grams per litre.
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.
How many millimoles are in 12g of sodium hydroxide?
The molecular weight of sodium hydroxide is 40g/mol. To get the amount of moles, you have to divide the weight by molecular mass. 12g / 40 is 0.3 moles. This is 300 millimoles.
How do you convert 0.85 g of calcium to mmol?
You look up the atomic weight for calcium, which is equivalent to the number of grams per mole. Then you divide the 0.85 g by this number, to get the number of moles. From there, it should be easy to convert to millimoles.
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.
