Question

A chemist uses 4.0 l of sulfuric acid solution to produce 3.2 gram of product. how much of the same sulfuric acid solution is needed to produce 8.0 gram of product?

Answer 1

Answer: 10 L

Explanation:

Given : 3.2 grams of product require 4.0 L of sulphuric acid

Asked : 8.0 grams of product require how many liters of same sulphuric acid

Thus using Unitary method:

3.2 grams of product require sulphuric acid = 4.0 Liters

Thus 8.0 grams of product require sulphuric acid = $\frac{4.0}{3.2}\times 8.0 g=10 Liters$

Answer 2

4 l ------ 3,2 g
x l ------ 8 g

x = 8 g × 4 l / 3,2 g = 10 l

Answer: 10 l of sulfuric acid is needed to produce 8 g of product.
