Calculate the mass in grams of 0.0086 mol of xenon (show the steps please)
To calculate the mass in grams of a given amount of a substance, you need to know the molar mass of the substance. The molar mass of xenon (Xe) is known to be 131.29 g/mol.
Here are the steps to calculate the mass in grams of 0.0086 mol of xenon:
Step 1: Start with the given value of moles of xenon (0.0086 mol).
Step 2: Use the molar mass of xenon (131.29 g/mol) to convert moles to grams.
Mass (g) = Number of Moles (mol) × Molar mass (g/mol)
Mass (g) = 0.0086 mol × 131.29 g/mol
Step 3: Calculate the result.
Mass (g) = 1.12914 g (rounded to four decimal places)
Therefore, the mass in grams of 0.0086 mol of xenon is approximately 1.1291 grams.
To calculate the mass in grams of xenon, we will use the molar mass of xenon and the given amount in moles.
Step 1: Find the molar mass of xenon (Xe) from the periodic table. The atomic mass of xenon (Xe) is approximately 131.29 g/mol.
Step 2: Multiply the molar mass of xenon by the given number of moles.
Mass (g) = number of moles × molar mass (g/mol)
Mass (g) = 0.0086 mol × 131.29 g/mol
Step 3: Perform the calculation to find the result.
Mass (g) = 1.1299 g
Therefore, the mass in grams of 0.0086 mol of xenon is approximately 1.1299 grams.
