The molecular mass of fluorine gas, F2 is 2(19.0) = 38.0Amount of F2 = mass of sample/molar mass = 9.5/38.0 = 0.25mol
There are 0.25 moles of fluorine in a 9.5g pure sample.
45g = 0.045kg
To calculate the number of moles in 2.35g of water, first determine the molar mass of water (H2O). The molar mass of one mole of water is approximately 18.015 g/mol. Use this molar mass to convert grams to moles: 2.35g / 18.015 g/mol = 0.13 moles of water.
Boron trifluoride is BF3. So each mole of BF3 contains 1 moles of boron (B) and 3 moles of fluorine (F). Thus, 3 moles of BF3 contains NINE moles of fluorine.
To find the number of moles in 1.01e23 fluorine atoms, divide the given number of atoms by Avogadro's number, which is approximately 6.022e23. So, 1.01e23 F atoms / 6.022e23 atoms/mol ≈ 0.168 moles of F atoms.
16 grams of oxygen how many moles is 0,5 moles.
45.
45g = 0.045kg
45g = 1.587oz
45g = 1.59oz
45g is about 25.39 drams.
1.59 oz.
45g = 1.59oz
0.8 moles Explanation: from the equation we can see, 2 mole A l is needed to react completely with 3 mole F e O so, 3 moles of F e O needs 2 moles A l so, 1 mole F e O needs 2 3 moles A l so, 1.2 mol F e O needs 2 × 1.2 3 moles A l = 0.8 moles A l
To calculate the number of moles in 2.35g of water, first determine the molar mass of water (H2O). The molar mass of one mole of water is approximately 18.015 g/mol. Use this molar mass to convert grams to moles: 2.35g / 18.015 g/mol = 0.13 moles of water.
To find the number of moles in 76 grams of fluorine, you first need to determine the molar mass of fluorine, which is approximately 19 grams per mole. Then, you divide the given mass (76 grams) by the molar mass of fluorine to get the number of moles. In this case, 76 grams of fluorine is equal to approximately 4 moles.
Boron trifluoride is BF3. So each mole of BF3 contains 1 moles of boron (B) and 3 moles of fluorine (F). Thus, 3 moles of BF3 contains NINE moles of fluorine.
There are 45 grams in 45g. Grams (g) is a unit of measurement for mass in the metric system. When you state "45g," you are already referring to 45 grams, so there is no need for conversion or calculation in this case.
