To find the number of moles of methane used, we first need to convert the mass of methane given (10.50g) to moles.
Step 1: Calculate the molar mass of methane (CH4)
Molar mass of CH4 = 12.01 g/mol (C) + 4(1.01 g/mol) = 16.04 g/mol
Step 2: Calculate the number of moles of methane
Number of moles = mass / molar mass
Number of moles = 10.50 g / 16.04 g/mol ≈ 0.6546 mol
Therefore, approximately 0.655 moles of methane are used.
The anesthetic chloroform (CHCI3, molar mass=119.36 g/mol) can be prepared by the reaction of methane CH4 molar mass= 16.04 g/mol with chlorine according to the following balanced equation: CH4+3CI2 CHCI3+3HCI
Assuming 10.50g of methane and 20.50g of chlorine are used, answer the following questions:
How many moles of methane are used? Be sure your answer has the correct number of significant figures.
