How many formula units of sodium acetate are in 0.87 moles of sodium acetat
To find the number of formula units in 32.0 g of magnesium chloride (MgCl2), you first need to calculate the molar mass of MgCl2. The molar mass of MgCl2 is 95.21 g/mol. Next, divide the given mass by the molar mass to get the number of moles, and then use Avogadro's number to convert moles to formula units. So, 32.0 g / 95.21 g/mol ≈ 0.336 moles of MgCl2, and then using Avogadro's number, this corresponds to approximately 2.02 x 10^23 formula units of MgCl2.
To find the number of formula units of magnesium oxide in 5.68 moles, you first need to determine the formula of magnesium oxide (MgO). Then use Avogadro's number (6.022 x 10^23) to convert moles to formula units. So, in 5.68 moles of MgO, there are approximately 3.43 x 10^24 formula units.
Since both chloride anions and nitrate anions have a charge of -1, there will be the same number of moles of silver chloride produced as the moles of silver nitrate reacted. (Since both silver nitrate and silver chloride are ionic compounds, it would be preferable to call their "moles" "formula units" instead.)
The gram formula unit mass of sodium chloride is 58.443, and every gram formula unit mass contains Avogadro's Number, 6.022 X 1023 formula units. Therefore, the mass sought is 58.443 X (4.59 X 1024)/(6.022 X 1023) or 445 grams, to the justified number of significant digits.
A same number.
The answer is 32,4.10e23.
A formula unit of salt, such as sodium chloride (NaCl), represents one mole of the compound. Therefore, if you have 10 moles of salt, you have 10 formula units of NaCl. In other words, for every mole of salt, there is one corresponding formula unit. Thus, 10 moles of salt correspond to 10 formula units.
The relative molecular mass of magnesium chloride is approximately 60. The molar mass is therefore 60g per mole. Therefore there is 0.42mol of formula units in 2.5 grams.The formula mass of MgCl2 is 24.3 + 2(35.5) = 95.3Amount of MgCl2 = 2.5/95.3 = 0.0262molThere are 0.0262 moles of formula unit in 2.5 grams of magnesium chloride.To get the number (not in moles), multiply the amount in moles by the Avogadro's constant.
To find the number of formula units in 33.8g of magnesium chloride (MgCl2), you first need to calculate the molar mass of MgCl2. The molar mass of MgCl2 is 95.21 g/mol. Then, divide the given mass by the molar mass to find the number of moles, which is 0.355 moles. Finally, multiply the number of moles by Avogadro's number (6.022 x 10^23) to find the number of formula units.
To determine the number of formula units, you need to first calculate the molar mass of magnesium chloride (MgCl2). The molar mass is 95.21 g/mol. Next, divide the given mass (25.2 g) by the molar mass to find the number of moles of magnesium chloride. Finally, use Avogadro's number (6.022 x 10^23) to convert moles to formula units.
To determine the number of formula units in 12.2g of magnesium chloride, you need to first calculate the molar mass of magnesium chloride (MgCl2). The molar mass of MgCl2 is 95.21 g/mol. Next, divide the given mass (12.2g) by the molar mass of MgCl2 to find the number of moles present. Finally, use Avogadro's number (6.022 x 10^23) to convert moles to formula units.
0.688 moles*6.02x1023=4.14x1023 Formula units
To find the number of formula units in 25.6 g of magnesium chloride (MgCl2), first calculate the molar mass of MgCl2 (95.21 g/mol). Then divide the given mass by the molar mass to find the number of moles (0.269 mol). Finally, use Avogadro's number (6.022 x 10^23 units/mol) to convert moles to formula units, resulting in approximately 1.62 × 10^23 formula units in 25.6 g of MgCl2.
To determine the number of formula units in 32.2 g of magnesium chloride (MgCl2), you need to first calculate the molar mass of MgCl2. The molar mass of MgCl2 is 95.21 g/mol. Then, divide the given mass by the molar mass to find the number of moles, and finally, use Avogadro's number (6.022 × 10^23) to convert moles to formula units.
