repares in-flight meals for a number of major airlines. One of the company’s products is grilled salmon with new potatoes and mixed vegetables. During the most recent week, the company prepared 6,700 of these meals using 1,300 direct labor-hours. The company paid its direct labor workers a total of $16,900 for this work, or $13.00 per hour. According to the standard cost card for this meal, it should require 0.20 direct labor-hours at a cost of $12.50 per hour. Required: 1. What is the standard labor-hours allowed (SH) to prepare 6,700 meals? 2. What is the standard labor cost allowed (SH × SR) to prepare 6,700 meals? 3. What is the labor spending variance? 4. What is the labor rate variance and the labor efficiency variance?

We will produce 2.87 * 10³ grams CO2 and 1.76 *10³ grams H2O

Explanation:

Step 1: Data given

Mass of C2H6O = 150.0 grams

Molar mass of C2H6O = 46.07 g/mol

Step 2: The balanced equation

C2H6O + 3O2 → 2CO2 + 3H2O

Step 3: Calculate moles C2H6O

Moles C2H6O = mass C2H6O / molar mass C2H6O

Moles C2H6O = 150.0 grams / 46.07 g/mol

Moles C2H6O = 3.256 moles

Step 4: Calculate moles products

For 1 mol C2H6O we need 3 moles O2 to produce 2 moles CO2 and 3 moles H2O

For 3.256 moles C2H6O we'll have 2*3.256 = 6.512 moles CO2

For 3.256 moles C2H6O we'll have 3 * 3.256 = 9.768 moles H2O

Step 5: Calculate mass of products

Mass CO2 = 6.512 moles * 44.01 g/mol = 286.6 grams = 2.87 * 10³ grams

Mass H2O = 9.768 moles * 18.02 g/mol = 176.0 grams = 1.76 *10³ grams

We will produce 2.87 * 10³ grams CO2 and 1.76 *10³ grams H2O
