The formula mass of the ionic compound lithium chloride, LiCl is 6.9 + 35.5 = 42.4.Amount of LiCl = 98.2/42.4 = 2.32mol
There are 2.32 moles of formula unit in a 98.2g pure sample of LiCl.
To get the numerical number, multiply the quantity in moles by the Avogadro's constant.
To find the number of moles in 0.550 grams of LiCl, divide the mass by the molar mass of LiCl, which is approximately 42.4 g/mol. 0.550 g LiCl / 42.4 g/mol LiCl ≈ 0.013 mol LiCl. Therefore, the student has approximately 0.013 moles of LiCl.
To calculate the number of grams of LiCl required, you need to use the formula: ( \text{grams} = \text{Molarity} \times \text{Volume} \times \text{Molar Mass} ) Given that the molar mass of LiCl is approximately 42.39 g/mol, plug in the values and calculate the grams of LiCl needed.
How many formula units of sodium acetate are in 0.87 moles of sodium acetat
LiCl does not have any loaned pairs of electrons. In LiCl, lithium donates one electron to chlorine to form an ionic bond, leading to a full outer shell for both elements.
To calculate the number of formula units in 5.6 g of H2S, you first need to determine the molar mass of H2S, which is 34.08 g/mol. Then, you can use the formula: Number of formula units = (mass given / molar mass) * Avogadro's number. Plugging in the values, you get: (5.6 g / 34.08 g/mol) * 6.022 x 10^23 = 9.89 x 10^22 formula units in 5.6 g of H2S.
42.394 grams.
127.17 g LiCl x 1 mol/42.4 g x 6.02x10^23 Form.Units/moles = 1.81x10^24 Formula Units.
127.17 g LiCl x 1 mol/42.4 g x 6.02x10^23 Form.Units/moles = 1.81x10^24 Formula Units.
To determine the number of molecules in a sample of LiCl, we need to first calculate the number of moles using the molar mass of LiCl (42.39 g/mol). Next, we use Avogadro's number (6.022 x 10^23 molecules/mol) to convert moles to molecules. In this case, there are approximately (127.17 \text{ g} / 42.39 \text{ g/mol} \approx 3 \text{ moles} \times 6.022 \times 10^{23} \text{ molecules/mole} ≈ 1.8 \times 10^{24}) molecules of LiCl in 127.17 g.

To make a 4M solution in 20 ml, you would need 0.32 grams of LiCl. This can be calculated using the formula: moles = molarity x volume (in L), then converting moles to grams using the molar mass of LiCl.
To find the number of moles in 0.550 grams of LiCl, divide the mass by the molar mass of LiCl, which is approximately 42.4 g/mol. 0.550 g LiCl / 42.4 g/mol LiCl ≈ 0.013 mol LiCl. Therefore, the student has approximately 0.013 moles of LiCl.
