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
How do you calculate the number of moles in 56 millimole Na-OH?
Milli means one thousandth. So there are 1000 millimoles in a mole. Therefore 56/1000 gives you 0.056 moles.
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 many Cu atoms are their in3.7x103 millimole?
To find the number of copper (Cu) atoms in 3.7 x 10^3 millimoles, you can use Avogadro's number, which is 6.022 x 10^23 atoms per mole. First, convert millimoles to moles (3.7 x 10^3 millimoles = 3.7 moles), then multiply by Avogadro's number to get the number of atoms (3.7 moles * 6.022 x 10^23 atoms/mole).
HOW DO YOU CONVERT mMOL INTO PERCENT?
To convert millimoles (mM) into a percentage, you first need to know the total volume of the solution in liters. Calculate the number of moles by dividing the millimoles by 1,000. Then, divide the number of moles by the total number of moles in the solution and multiply by 100 to get the percentage concentration. The formula is: ((\text{mM} / \text{Total mM}) \times 100).
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 do you convert moles per liter into millimoles per liter?
Depends. It sounds like a vague question. Say you wanted to know how mLs are in 1mol of pure water @ 25c. 1mol of water is 18g. The density of water is 1g/1ml. So 1mol of water is 18mL. So convert the amount of moles into grams. And times the amount of grams by the density. M x D = mL Or if you want to know how many mLs are in 2mols of 0.5mol/L solution. Which is is 4000mL btw. You would divide the amount in moles by the molarity of the solution. N / C = mL Hope I have been somewhat helpful :)
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
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.
