how do i convert 2.23*10 22 formula units to moles?
2.23E22/6.02E
23 = ?
To convert formula units to moles, you need to use Avogadro's number (6.022 x 10^23). Here are the steps to convert 2.23 x 10^22 formula units to moles:
1. Identify the number of formula units: In this case, it is 2.23 x 10^22 formula units.
2. Determine the number of moles: To convert formula units to moles, divide the number of formula units by Avogadro's number.
Number of moles = Number of formula units / Avogadro's number
Plugging in the values, we have:
Number of moles = 2.23 x 10^22 / (6.022 x 10^23)
3. Simplify the expression by dividing the numerator and denominator by 10^22:
Number of moles = (2.23 / 6.022) x (10^22 / 10^23)
Number of moles = 0.3698 x 0.1
Number of moles ≈ 0.03698 moles
Therefore, 2.23 x 10^22 formula units is approximately equivalent to 0.03698 moles.
To convert formula units to moles, you need to use Avogadro's number. Avogadro's number, represented by the symbol "Nₐ" or "L", is defined as 6.022 x 10²³ (atoms or molecules) per mole. Here's how you can convert 2.23 x 10²² formula units to moles:
Step 1: Identify the conversion factor
For every 6.022 x 10²³ formula units, there is 1 mole. This is the conversion factor we will use.
Step 2: Set up the conversion equation
Write down the given value and set up a conversion equation using the conversion factor. Take note of the units and how they will cancel out in the equation. In this case, the formula units unit will cancel out, leaving us with moles.
(2.23 x 10²² formula units) x (1 mole / 6.022 x 10²³ formula units)
Step 3: Perform the calculation
Multiply the given value by the conversion factor and cancel out the units:
(2.23 x 10²²) x (1 / 6.022 x 10²³) = 0.0370 moles
Step 4: Round the answer
Finally, round the number of moles to the appropriate number of significant figures. In this case, the answer should be rounded to four significant figures:
0.0370 moles (rounded to four significant figures)
So, 2.23 x 10²² formula units is equivalent to approximately 0.0370 moles.
