Chapter 3, Problem 61
Calculate the number of moles in each sample: a. 72.5 g CCl4 b. 12.4 g C12H22O11 c. 25.2 kg C2H2 d. 12.3 g dinitrogen monoxide
Verified step by step guidance1
insert step 1: Identify the molar mass of each compound.
insert step 2: Use the formula for moles: \( \text{moles} = \frac{\text{mass (g)}}{\text{molar mass (g/mol)}} \).
insert step 3: For each compound, divide the given mass by its molar mass to find the number of moles.
insert step 4: For CCl4, calculate the molar mass by adding the atomic masses of 1 C and 4 Cl atoms.
insert step 5: Repeat the process for C12H22O11, C2H2, and dinitrogen monoxide, using their respective molar masses.
