How many moles are present in 355 grams of Au?
To find the number of moles in 355 grams of Au, you need to divide the given mass by the molar mass of gold (Au). The molar mass of Au is approximately 197 grams/mol. Therefore, 355 grams of Au is equivalent to 355/197 = approximately 1.80 moles of Au.
How many moles are in 42 grams of CO2?
To calculate the number of moles in 42 grams of CO2, we first need to find the molar mass of CO2, which is approximately 44 grams per mole. Then, divide the given mass by the molar mass to find the number of moles. In this case, 42 grams of CO2 is equivalent to 42/44 = 0.955 moles.
How many grams of fructose are in 1.20 moles of fructose?
The molar mass of fructose is approximately 180.16 g/mol. To find the mass in grams, you would multiply the number of moles (1.20 mol) by the molar mass (180.16 g/mol). Therefore, 1.20 moles of fructose would be 216.19 grams.
How many moles of K2SO4 are in 15.0 grams of K2SO4?
To find the number of moles of K2SO4 in 15.0 grams, first calculate the molar mass of K2SO4 (K: 39.10 g/mol, S: 32.07 g/mol, O: 16.00 g/mol). Molar mass of K2SO4 = 2(39.10) + 32.07 + 4(16.00) = 174.26 g/mol Now, divide the given mass by the molar mass to find the number of moles: 15.0 g / 174.26 g/mol = 0.086 moles of K2SO4
How many grams of H3PO4 are produced when 10.0 moles of water react with an excess of P4O10?
1 mole of P4O10 reacts with 6 moles of water to produce 4 moles of H3PO4. Therefore, 10.0 moles of water will produce (10/6)*4 moles of H3PO4. To convert moles to grams, multiply the number of moles by the molar mass of H3PO4.
How many grams of CaBr2 are there in 0.31moles of CaBr2?
To find the number of grams of CaBr2 in 0.31 moles, you first calculate the molar mass of CaBr2, which is approximately 199.89 g/mol. Then, you can multiply the number of moles (0.31 moles) by the molar mass to find the grams: 0.31 moles x 199.89 g/mol = 61.97 grams of CaBr2.
How many moles of CaBr2 are in 5.0 grams of CaBr2?
Well, darling, if you want to know how many moles of CaBr2 are in 5.0 grams, you just need to divide the mass by the molar mass of CaBr2. The molar mass of CaBr2 is approximately 199.89 g/mol, so 5.0 grams of CaBr2 is roughly 0.025 moles. Hope that helps, sugar!
How many moles are in 1.2 kilograms of calcium bromide?
To find the number of moles in 1.2 kg of calcium bromide, you first need to determine the molar mass of calcium bromide (CaBr2), which is approximately 199.89 g/mol. Then convert the mass of 1.2 kg to grams (1200 g). Finally, divide the mass in grams by the molar mass to find the number of moles. In this case, 1200g / 199.89g/mol ≈ 6 moles of calcium bromide.
How many moles are in 7.4 kilogram of calcium bromide?
That is a lot of calcium bromide we are dealing with. The formula mass of calcium bromide, CaBr2 is 40.1 + 2(79.9) = 199.9.Amount of CaBr2 = (7.4 x 1000)/199.9 = 32.0mol There are 32 moles of calcium bromide in a 7.4kg pure sample.
What is 16 grams of oxygen how many moles?
16 grams of oxygen how many moles is 0,5 moles.
What mass of calcium bromide is needed to prepare 150.0 mL of a 3.50 M solution?
To calculate the mass of calcium bromide needed, you would first find the number of moles needed using the equation moles = Molarity * Volume (in liters). Then, you would use the molar mass of calcium bromide to convert moles to grams. The molar mass of calcium bromide is 199.89 g/mol.
