Question

How many moles of propylene (c3h6) are in 25.0 g

Answer 1

To find the number of moles of propylene (C3H6) in a 25.0 g sample, you can use the formula moles = mass (g) / molar mass (g/mol)

Step-by-step explanation:

To find the number of moles of propylene (C3H6) in a 25.0 g sample, we need to use the molar mass of propylene. The molar mass of propylene can be calculated by adding up the atomic masses of its individual elements:

• C (carbon) has a molar mass of 12.01 g/mol
• H (hydrogen) has a molar mass of 1.01 g/mol

So, the molar mass of propylene (C3H6) is:

(3 * 12.01 g/mol) + (6 * 1.01 g/mol) = 42.09 g/mol

Next, we can use the formula:

moles = mass (g) / molar mass (g/mol)

Substituting the given values into the formula:

moles = 25.0 g / 42.09 g/mol = 0.594 moles (rounded to three decimal places)
