How many grams are in 0.02 moles of beryllium iodide BeI2?
To find the mass in grams of 0.02 moles of beryllium iodide (BeI₂), we first calculate its molar mass. The molar mass of beryllium (Be) is approximately 9.01 g/mol, and iodine (I) is about 126.90 g/mol. Thus, the molar mass of BeI₂ is 9.01 + (2 × 126.90) = 262.81 g/mol. Therefore, 0.02 moles of BeI₂ would weigh approximately 0.02 × 262.81 = 5.26 grams.
Convert grams to moles?
To convert grams to moles, you need to know the molar mass of the substance. Divide the given mass in grams by the molar mass to find the number of moles. This calculation is done using the formula: moles = grams / molar mass.
Find the mass in grams of 1.54 moles of H2O?
To find the mass of 1.54 moles of H2O, you can use the molar mass of water. The molar mass of H2O is 18.015 grams/mol. Therefore, the mass of 1.54 moles of H2O would be 1.54 moles * 18.015 grams/mol = approximately 27.75 grams.
What is the mass in grams of 1.92 moles of uranium atoms What if your answer?
To find the mass of 1.92 moles of uranium atoms, you can use the molar mass of uranium, which is approximately 238 grams per mole. Multiply the number of moles by the molar mass: 1.92 moles × 238 g/mole = 456.96 grams. Therefore, the mass of 1.92 moles of uranium atoms is about 457 grams.
How is the mass in grams converted in to moles?
mol = mass/Mr If the Mr and number of moles of a substance is known then the mass can be calculated. example:- if we have 1 mole of Na, how many grams do we have? mass = mol x Mr mass = 1 x 23 mass = 23g
How many grams are in 0.02 moles of beryllium iodide moles of beryllium iodide?
To find the number of grams in 0.02 moles of beryllium iodide (BeI2), you would first calculate the molar mass of BeI2, which is 262.83 g/mol. Then, you would multiply the molar mass by the number of moles: 0.02 moles * 262.83 g/mol = 5.26 grams of beryllium iodide.

How many grams are in 1.24 moles of beryllium?
There are 2.04 vaginas in a mole so techinically speaking there 5 7 moles in your moms vagina! which mean thats 7 moles will die from lack of food! which they will then weigh .6grams each. So 7 times 2.04 vaginas is 14.28 moles. Then you take 14.28 moles times .6 grams which equals sperm! :P
How many moles are in 89.0 grams of aluminum?
all you have to do to fine the moles of any element is divide the given grams by the molar mass (which you can find on a periodic table of elements) Likewise, if you need to find the grams, just multiply the number of moles by molar mass. moles = grams/molar mass grams = moles x molar mass your equation should look like this: moles = 89.0 / 17.0 moles = .471
Mass of 3 moles of ammonia?
Molar mass of ammonia = (14.01 + 3.03) (Molar mass of nitrogen + 3 times molar mass of hydrogen, as chemical formula of ammonia is NH3). Molar mass= 17.04 Molar mass x moles = mass 17.04 x 3 = 51.12 Mass of 3 moles of ammonia is 51.12g.
How many grams are in 2.8 moles of gold?
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.
Which mathematical relationship should you use to convert moles of a substance into grams?
You can use the molar mass of the substance to convert moles into grams. This involves multiplying the number of moles by the molar mass of the substance, where the molar mass is expressed in grams per mole. This relationship allows you to convert between the two units.
How many moles in 2.3 grams of phosphorus?
mole = mass/molar mass mass=2.3 grams molar mass=30.97 2.3/30.97=0.0742 moles
Mass in grams if the molar mass of sodium sulfate is 141.98 gramsmoles?
To calculate the mass in grams of sodium sulfate, we need to know the number of moles. Once we have the number of moles, we can multiply it by the molar mass to find the mass in grams. For example, if we have 2 moles of sodium sulfate, the mass would be 2 moles * 141.98 grams/mole = 283.96 grams.
Which statement shows how to correctly convert from the mass of a compound in grams to the amount of that compound in moles?
To convert from the mass of a compound in grams to the amount of that compound in moles, you need to divide the mass of the compound in grams by its molar mass (which is found on the periodic table). This will give you the number of moles of the compound. The formula to use is: moles = mass (g) / molar mass.
What is the molar mass of 2 moles of 03?
