Question

An experiment requires 42.5 g of sulfuric acid, which is easier to measure by volume than by mass what voliume should be measured out if the denstiy of the sulfuric acid is 1.84

Answer 1

The volume of liquid is 23.098 mL.

Step-by-step explanation:

To calculate mass of a substance, we use the equation:

`\text{Density of substance}=\frac{\text{Mass of substance}}{\text{Volume of substance}}`

We are given:

Density of sulfuric acid= 1.84 g/mL

Mass of sulfuric acid =42.5 g

Putting values in above equation, we get:

`1.84 g/mL=\frac{42.5 g}{\text{Volume of liquid}}\\\\\text{Volume of liquid}=15.13mL`

Hence, the volume of liquid is 23.098 mL.

Answer 2

Using proportions, if x is the unknown volume we have:
1.84 / 1 = 42.5 / x

Multiply both sides above by x:
1.84*x / 1 = 42.5
1.84*x = 42.5
Divide both sides by 1.84:
x = 42.5 / 1.84

X = 23.10 mL
