Question

What is the mass of 6.8 moles of C2H2O? Round your answer to two decimal places.

Answer 1

Mass = 285.74 g

Step-by-step explanation:

Given data:

Moles of C₂H₂O = 6.8 mol

Mass of C₂H₂O = ?

Solution:

Number of moles = mass/ molar mass

Molar mass of C₂H₂O = 42.02 g/mol

Now we will put the values in formula:

Mass = number of moles × molar mass

Mass = 6.8 mol × 42.02 g/mol

Mass = 285.74 g
