Calculating the Number of Lemon Citric Acid Packets Needed for Pickling

To calculate the number of lemon citric acid packets needed for pickling 3 liters of marinade, we can use the given information that 1 liter of water requires 19g of lemon citric acid and that the lemon citric acid is sold in packets of 20g each.

Given: - 1 liter of water requires 19g of lemon citric acid. - Lemon citric acid is sold in packets of 20g each.

Calculation:

To find the amount of lemon citric acid needed for 3 liters of marinade, we can use the following calculation:

1. Calculate the total amount of lemon citric acid needed for 3 liters of marinade: - 3 liters * 19g/liter = 57g

2. Determine the number of packets needed: - Since each packet contains 20g of lemon citric acid, we can calculate the number of packets needed: - 57g / 20g/packet = 2.85 packets

Answer:

To prepare 3 liters of marinade, at least 3 packets of lemon citric acid need to be purchased.
