Given that,
Volume, d = 2 mL
Mass, m = 18 grams
We have to find the density. Density of an object is equal to mass per unit volume. It can be given by:
So, the density is 9 g/cm³.
Answer:
Option A (0.043 g) is the correct answer.
Explanation:
Given:
= 43 mg
As we know,
then,
⇒
Thus, the above is the correct alternative.
Answer: An oxygen atom in heavy water has an extra neutron. A hydrogen atom in heavy water has an extra proton.
Explanation:
Answer: Option (A) is the correct answer.
Explanation:
Viscosity is defined as the ability of a liquid to resist its flow. When a substance has high viscosity then it is known as a viscous substance.
Also, more is the mass of a substance more will be its resistance to move from one place to another.
- Mass of hexane is 86.18 g/mol
- Mass of is 60.09 g/mol
- Mass of is 74.12 g/mol
- Mass of is 40.06 g/mol
Mass of is 62.07 g/mol
Therefore, out of the given options viscosity of hexane is the greatest.
