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 many argon atoms are contained in 7.66x105 mmol of argon?

To find the number of argon atoms, we first need to convert the amount from millimoles to moles by dividing by 1000. Next, we use Avogadro's number, which is 6.022 x 10^23 atoms/mol, to calculate the number of atoms in 7.66 x 10^2 moles of argon. The result is approximately 4.61 x 10^26 argon atoms.

How many moles of solute are contained in the following solution 17.33 mL 2.17 M CaCl2?

To find the moles of solute, first calculate the amount of CaCl2 in the solution: 17.33 mL * 2.17 mol/L = 37.6561 mmol of CaCl2. Then convert this to moles: 37.6561 mmol / 1000 = 0.0377 mol of CaCl2 in the solution.


How do you convert mmol to nmol?

To convert from mmol (millimoles) to nmol (nanomoles), you simply multiply the value in mmol by 1000000. This is because there are 1000000 nmol in 1 mmol.


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
