What is the limiting reactant in 2Al plus 3Cl2 equals 2AlCl3?
moles of Al=4.40 g/26.9815 g/mol=0.163 moles cl2=15.4g/70.906g/mol=0.217 the ratio is 2:3 cl2 is the limiting reagent
How many milligrams of sodium make one gram of salt?
Formula for table salt = NaCl 1.00 g = 1.00 / 58.45 mol = 1.71 x 10-2 mol Mole Na required = 1.71 x 10-2 mol Mass of Na = 1.71 x 10-2 mol x 23.0 g /mol = 0.393 g = 393 mg
Consider the equation 2a plus b--a2b if you mix 1.0 mol of a and 1.0 mol of b how many moles of a2b can be produced?
Because it takes 2a to make 1mol of a2b, the ratio is 1mol a2b/2mol a. If you only have 1.0 mol of a to react, then 1mol a x (1mol a2b/2 mol a)= 0.5 mol of a2b Because it takes 1 mol of b to make 1 mole of a2b, the ratio is 1mol a2b/1mol b. So, 1.0 mol b x (1mol a2b/1mol b)= 1.0 mol of a2b. Since you run out of a to react with b, a is the limiting reagent meaning that you can only produce 0.5 mol of a2b even though you have an excess amount of b. So, only 0.5 mol of a2b can be produced.
What is faraday constant?
•96485 coulomb/mol of electrons (for J) •23054 C/mol (for Cal) •23.054 C/mol (for kCal) •
Is the concentration of H plus in solution given the OH equals 2.54 x 10-4?
[H+] = Kw / [OH-] = 1.0*10-14 / 2.5*10-4 = 4.0*10-11 mol/L
How many mmol are in 3.5 mol?
There are 3500 mmol in 3.5 mol. To convert mol to mmol, you multiply by 1000 since there are 1000 mmol in 1 mol.
What is 25 mmol converted to mol?
25 mmol is equal to 0.025 mol.
How do you convert mmol to milliters?
1 mol = 103 mmol Conversely, 1 mmol = 10-3 mol For example: 25 mol x 103 mmol/1 mol = 25000 mmol and, 3.2 mmol x 10-3 mol/1 mmol = 0.0032 mol
2.55 mmol to moles?
To convert mmol to moles, divide by 1000. Therefore, 2.55 mmol is equal to 0.00255 moles.
Convert mmol to mol?
1 mEq=1 mmol/valence e.g.For sodium, 1 mEq=1mmol/1 (valence of sodium=1) means, 1 mmol sodium=1 mEq of sodium take for calcium,valence=2 1 1 mEq of calcium=1mmol/2=0.5 mmol of calcium
How many grams of salt is 80 mmol sodium?
To convert mmol to grams, multiply by the molar mass. The molar mass of sodium is approximately 23 g/mol. Therefore, 80 mmol of sodium is equal to 80 mmol * 23 g/mol = 1840 grams of salt (sodium chloride).
How many grams are equal to 450 milligrams?
Molarity = moles of solute/Liters of solution ( 450 ml = 0.450 liters) 5M C6H12O6 = moles C6H12O6/0.450 liters = 2.25 moles C6H12O6 (180.156 grams/1 mole C6H12O6) = 405.351 grams of glucose ( you do significant figures )
How many argon atoms are contained in 7.66 x 105 mmol of argon?
To find the number of argon atoms, we first need to convert mmol to moles by dividing by 1000. Then we use Avogadro's number (6.022 x 10^23 atoms/mol) to calculate the number of argon atoms. Therefore, number of argon atoms = (7.66 x 10^5 mmol / 1000) x 6.022 x 10^23 atoms/mol
How do you covert sodium from mg to mmol?
To convert sodium from mg to mmol, you need to divide the amount in milligrams by the molar mass of sodium (22.99 g/mol) to get the amount in millimoles. The formula is: mmol = (mg ÷ molar mass of sodium).
What is the symbol for milli moles?
n, is the symbol for the amount measured in moles in the ideal gas equation. The abbreviation for mole is mol (not much of an abbreviation).
How do you convert from mg to mmol if MW of creatinine is 113?
To convert from mg to mmol for creatinine, you need to know the molecular weight (MW) of creatinine, which is 113 g/mol. To convert, divide the mass in milligrams (mg) by the molecular weight in milligrams per mmol (113 mg/mmol). For example, if you have 100 mg of creatinine, the conversion would be 100 mg / 113 mg/mmol = 0.88 mmol.
What is the formula to convert gm to mmol per liter?
To convert grams (g) to millimoles per liter (mmol/L) for a substance, you need to know the molar mass of the substance. Then you can use the formula: Concentration in mmol/L = (mass in g) / (molar mass in g/mol) * 1000.
