Question

Question 20
A graduated cylinder contains 100 mL of a liquid. The mass of the
graduated cylinder with the liquid is 145 grams. The mass of the
graduated cylinder when empty is 45 grams. The liquid is most likely
O Chloroform (Density = 1.492 g/mL)
Water (Density = 1 g/mL)
O Corn oil Density = 0.925 g/mL)
O Ethanol (Density = 0.789 g/mL)

Answer 1

Answer:

Water

Explanation:

Mass of fluid is 145 - 45 g

                     = 100 g

Density of liquid:

$\frac{\text{mass of liquid}}{\text{volume of liquid}}$

Plug in:

$\frac{100\text{mg}}{100\text{ml}}$

$\frac{1\text{g}}{1\text{ml}}$

 = $1 \text{g}/{\text{ml}$

We know that 1 ml = 1 $cm^3$

• Density = 1 gm/cc

But density of water is 1 g/cc [at 20 degree Celsius]

Therefore, the answer is option B.
