How do you calculate the moles of water?
To calculate the moles of water, you can use the formula: moles = mass of water (in grams) / molar mass of water (about 18.015 g/mol). Simply divide the mass of water by its molar mass to find the number of moles.
How many moles are there in 5gram of sulphur?
To find the number of moles in 5 grams of sulfur, you need to divide the mass of the sample by the molar mass of sulfur. The molar mass of sulfur is approximately 32.06 g/mol. Therefore, 5 grams of sulfur would be equal to 0.156 moles.
How many moles of water are on 72.08g of H2O?
To determine the number of moles of water in 72.08g of H2O, we first need to calculate the molar mass of water (H2O). The molar mass of water is approximately 18.015 g/mol (2 hydrogen atoms with a molar mass of 1.008 g/mol each, and 1 oxygen atom with a molar mass of 16.00 g/mol). Next, we use the formula: moles = mass / molar mass. Plugging in the values, we get moles = 72.08g / 18.015 g/mol ≈ 4 moles of water. Therefore, there are approximately 4 moles of water in 72.08g of H2O.
What is the mass of 7 mole of h2o?
To find the mass of 7 moles of water (H₂O), first note that the molar mass of water is approximately 18 grams per mole. Therefore, the mass of 7 moles of water can be calculated by multiplying the number of moles by the molar mass: 7 moles × 18 g/mol = 126 grams. Thus, the mass of 7 moles of H₂O is 126 grams.
What mass of water is 2.000 mol of water?
The mass of 2 moles of water is 36 g.
What is the mass of 0.5 moles of water?
The mass of 0,5 moles of water is 9 g.
How many moles of oxygen are represent in 0.16 g of oxygen gas?
To find the number of moles of oxygen in 0.16 g of oxygen gas, you first need to determine the molar mass of oxygen (O2), which is about 32 g/mol. Then, you can use the formula moles = mass / molar mass to calculate the number of moles. In this case, 0.16 g / 32 g/mol = 0.005 moles of oxygen gas.
How do you calculate the moles of water?
To calculate the moles of water, you can use the formula: moles = mass of water (in grams) / molar mass of water (about 18.015 g/mol). Simply divide the mass of water by its molar mass to find the number of moles.
How much mass is in 1 mole of sulfur atoms?
Remember the Equation Moles = mass(g) / Ar (Relative Atomic Mass) Algebraically rearranging mass(g) = moles X Ar We have 1 mole and from the Periodic Table the Atomic Mass of Sulphur is '32'. Hence substituting mass(g) = 1 moles X 32 mass = 32 g .
How many moles are there in 5gram of sulphur?
To find the number of moles in 5 grams of sulfur, you need to divide the mass of the sample by the molar mass of sulfur. The molar mass of sulfur is approximately 32.06 g/mol. Therefore, 5 grams of sulfur would be equal to 0.156 moles.
What is the total mass of h2o produced when 32 grams of Cu is completely consumed?
To calculate the mass of water produced when 32 grams of copper is consumed, we need to use the stoichiometry of the reaction. Given the balanced chemical equation for the reaction of copper with water, we can determine the moles of copper reacting and then use the mole ratio to find the moles of water produced. Finally, using the molar mass of water, we can calculate the mass of water produced.
What mass of oxygen two moles of O2 molecules have molor mass of O2 is 32 grms per mole?
Two moles of O2 molecules would have a mass of 64 grams (2 moles x 32 grams/mole = 64 grams).
How would you find out how much 12.4 moles of water weigh?
Multiply moles by molecular mass of water (18), gives you 223.8g. Remember this formula: Number of moles = mass / molecular mass
How many moles of water are on 72.08g of H2O?
To determine the number of moles of water in 72.08g of H2O, we first need to calculate the molar mass of water (H2O). The molar mass of water is approximately 18.015 g/mol (2 hydrogen atoms with a molar mass of 1.008 g/mol each, and 1 oxygen atom with a molar mass of 16.00 g/mol). Next, we use the formula: moles = mass / molar mass. Plugging in the values, we get moles = 72.08g / 18.015 g/mol ≈ 4 moles of water. Therefore, there are approximately 4 moles of water in 72.08g of H2O.
How you calculate the mass of 1.5 moles of oxygen molecule?
To calculate the mass of 1.5 moles of oxygen molecules (O2), you multiply the number of moles (1.5) by the molar mass of oxygen (O2). The molar mass of O2 is approximately 32 g/mol. So, the mass of 1.5 moles of oxygen molecules would be 1.5 moles * 32 g/mol = 48 grams.
How many moles of water are in 0.34g of water?
To find the number of moles in 0.34g of water, you first need to calculate the molar mass of water, which is approximately 18g/mol. Then, divide the given mass by the molar mass to get the number of moles. Therefore, 0.34g / 18g/mol ≈ 0.019 moles of water.
How many moles of sulfur are present in a 16-g sample of sulfur?
To determine the number of moles of sulfur in a 16-g sample, you need to divide the mass by the molar mass of sulfur. The molar mass of sulfur is approximately 32 g/mol. Thus, 16 g/32 g/mol = 0.5 moles of sulfur in the sample.
