- 0.0175 g
- 0.035 g
- 17.5 g
- 35 g
Show Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Step 1: 350 ppm means 350 mg of SO2 is needed per kg of product.
Step 2: For 100 kg of squash, SO2 required = 350 x 100 = 35000 mg = 35 g.
Step 3: KMS is added at a rate that supplies this exact SO2 dose to the squash, so the quantity of KMS needed is 35 g.
Step 4: This matches option 4.
Step 2: For 100 kg of squash, SO2 required = 350 x 100 = 35000 mg = 35 g.
Step 3: KMS is added at a rate that supplies this exact SO2 dose to the squash, so the quantity of KMS needed is 35 g.
Step 4: This matches option 4.
