For this you need the atomic (molecular) mass of NaCl. Take the number of grams and divide it by the Atomic Mass. Multiply by one mole for units to cancel. NaCl=58.5 grams
38.0 grams NaCl / (58.5 grams) = .650 moles NaCl
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.
Well, darling, to find the number of formula units in 200 grams of Calcium Carbonate, you first need to calculate the molar mass of CaCO3. Once you do the math, you'll find that one mole of CaCO3 weighs 100.09 grams. So, 200 grams of CaCO3 represents 2 moles of the compound, which is equivalent to 2 times Avogadro's number (6.022 x 10^23) formula units. Voilà!
Use stoichiometry. 3.5g-> moles 22.99+16+1.0079=39.99 Now 3.5/39.99 = .088 moles of NaOH Now you can use avagadros number 6.022x10^23 .088 moles -> formula units .088/6.022x10^23 You should end up with 1.46x10-25 formula units. Yeah, I know, Chem sucks huh?
There is no direct relationship between grams of oxygenand atoms of oxygen. Use the atomic mass to convert grams to moles and Avogadro's number to convert moles to atoms.Since you are converting from grams O, this goes in the denominator (on the bottom) of the first factor. You want to end up in units of atoms of O, so this goes in the numerator (on the top) of the last factor.g O1.00 mole O6.02E+23 atom O= atoms O16.0 gram O1.00 mole ONote that the units grams oxygen "cancel out" in the first factor and you are left in units of moles. Moles cancel out in the second factor and the final units are atoms oxygen.
To calculate the number of moles of CaCl2, you first need to find the molar mass of CaCl2, which is 110.98 g/mol. Then, you divide the given number of formula units (1.261024) by Avogadro's number to convert it to moles. So, the answer would be approximately 1.14 moles of CaCl2.
To find the number of formula units in 22.4 grams of SnO2, you first need to determine the molar mass of SnO2, which is 150.71 g/mol. Next, calculate the number of moles in 22.4 grams using the formula: moles = mass / molar mass. Then, use Avogadro's number (6.022 x 10^23) to convert moles to formula units.
It depends on the substance and its molar mass.In order to convert from grams to formula units, you must first convert grams to moles, then moles to formula units (grams --> moles --> formula units).1.

No, you do not need to convert grams to moles when using the ideal gas law. The ideal gas law is typically used with moles of gas, but you can directly use grams by adjusting the units of the gas constant accordingly.
To find the number of moles of CaCl2 in 2.00x10^24 formula units, you need to first determine the molar mass of CaCl2, which is 110.98 g/mol. Then, divide the number of formula units by Avogadro's number (6.022x10^23) to convert to moles. This gives you approximately 3.32 moles of CaCl2.
42.394 grams.
To convert grams to moles, you divide the given mass in grams by the molar mass of the substance in grams per mole, which is obtained from the periodic table. This calculation gives you the number of moles present. Avogadro's number (6.022 x 10^23) is used to convert moles to individual particles or entities like atoms or molecules.
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.
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 calculate the number of formula units in 1.34g of CaO, we first need to find the molar mass of CaO. CaO has a molar mass of 56.08 g/mol. Next, we convert the given mass to moles using the formula: moles = mass / molar mass. Finally, we use Avogadro's number (6.022 x 10^23) to convert moles to formula units.
The molar mass of gold is approximately 197 grams/mol. To convert moles to grams, you multiply the number of moles by the molar mass. Therefore, 2.8 moles of gold would be approximately 2.8 * 197 = 551.6 grams.
