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.
How many moles are in 332.9 g of Ba(OH)2?
To find the number of moles in 332.9 g of Ba(OH)₂, first calculate its molar mass. The molar mass of Ba(OH)₂ is approximately 171.34 g/mol (with Ba = 137.33 g/mol and OH = 17.01 g/mol). Using the formula: moles = mass (g) / molar mass (g/mol), we get: moles = 332.9 g / 171.34 g/mol ≈ 1.94 moles. Thus, there are approximately 1.94 moles of Ba(OH)₂ in 332.9 g.
What is the molar mass of the sugar called glucose?
The molar mass of glucose is 180,16 g.
What is the equivalent mass of Fe(OH)3?
The equivalent mass of a compound is calculated by dividing its molar mass by the number of equivalents. For Fe(OH)₃, the molar mass is approximately 106.87 g/mol (Fe: 55.85 g/mol + 3 × O: 3 × 16.00 g/mol + 3 × H: 3 × 1.01 g/mol). Since Fe(OH)₃ can donate three hydroxide ions (OH⁻) in reactions, its equivalent mass is 106.87 g/mol ÷ 3, which is approximately 35.62 g/equiv.
Is the empirical formula molar mass less than or equal to the actual molar mass for all compound?
The empirical formula molar mass is the mass of the simplest whole-number ratio of the elements in a compound, while the actual molar mass corresponds to the molar mass of the compound's molecular formula. The empirical formula molar mass is always less than or equal to the actual molar mass because the empirical formula represents the smallest ratio of atoms, which can be multiplied to obtain the molecular formula. Therefore, for compounds with a molecular formula that is a multiple of the empirical formula, the empirical molar mass will be less than the actual molar mass.
How many moles are in 317.0 g of BaOH2?
To find the number of moles in 317.0 g of Ba(OH)2, first calculate the molar mass of Ba(OH)2 which is 171.34 g/mol. Then divide the given mass by the molar mass to get the number of moles. In this case, the number of moles would be 317.0 g / 171.34 g/mol ≈ 1.85 moles.
What is the percent compositor oxygen in Al(OH)?
The percent composition of oxygen in Al(OH)3 (aluminum hydroxide) is 35.77%. This is calculated by dividing the molar mass of oxygen by the molar mass of the compound and multiplying by 100.
What is the molar mass of sodium and hydroxide?
The molar mass of sodium (Na) is 22.99 g/mol, and the molar mass of hydroxide (OH) is 17.01 g/mol. To find the molar mass of sodium hydroxide (NaOH), you can add the molar masses of sodium and hydroxide together, which equals 39.00 g/mol.
What percent of oxygen is in the compound mgoh2?
The compound Mg(OH)2 contains 16% oxygen. This can be calculated by dividing the molar mass of oxygen by the molar mass of Mg(OH)2 and multiplying by 100.
How many moles are there in 150 grams of Al(OH)3?
To determine the number of moles in 150 grams of Al(OH)3, we first need to calculate the molar mass of Al(OH)3: Aluminum (Al) has a molar mass of 26.98 g/mol, oxygen (O) has a molar mass of 16.00 g/mol, and hydrogen (H) has a molar mass of 1.01 g/mol. Molar mass of Al(OH)3 = 26.98 + 3(16.00) + 3(1.01) = 78.03 g/mol Now, we can calculate the number of moles: Number of moles = Mass (g) / Molar mass Number of moles = 150 g / 78.03 g/mol ≈ 1.92 moles.
What is the percentage of oxgyen in Ba OH 2 x 8H2O?
Molar mass of all oxygen in compound/Total molar mass of compound * 100 = % oxygen in compound ==================
Molar mass of AlOH3?
The molar mass of AlOH3 is calculated by adding the atomic masses of each element in its chemical formula. Aluminum (Al) has a molar mass of 26.98 g/mol, oxygen (O) has a molar mass of 16.00 g/mol, and hydrogen (H) has a molar mass of 1.01 g/mol. Therefore, the molar mass of AlOH3 is 78.02 g/mol.
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.
What is the percentage of water to the nearest tenth in this compound BaOH2 8H2O?
The compound Ba(OH)2·8H2O has 8 water molecules associated with it. To find the percentage of water in the compound, calculate the molar mass of the water molecules (8H2O) and the molar mass of the entire compound (Ba(OH)2·8H2O). Then divide the molar mass of the water by the molar mass of the entire compound and multiply by 100 to get the percentage of water.
How many moles are in 332.9 g of Ba(OH)2?
To find the number of moles in 332.9 g of Ba(OH)₂, first calculate its molar mass. The molar mass of Ba(OH)₂ is approximately 171.34 g/mol (with Ba = 137.33 g/mol and OH = 17.01 g/mol). Using the formula: moles = mass (g) / molar mass (g/mol), we get: moles = 332.9 g / 171.34 g/mol ≈ 1.94 moles. Thus, there are approximately 1.94 moles of Ba(OH)₂ in 332.9 g.
How many moles of BaOH2 are in 2400 grams of BaOH 2?
To find the number of moles in 2400 grams of Ba(OH)2, divide the given mass by the molar mass of Ba(OH)2. The molar mass of Ba(OH)2 is 171.34 g/mol. So, 2400 g / 171.34 g/mol = 14.00 mol of Ba(OH)2.
