How do you Convert 19mL to pL?
s2008m [1.1K]

Picoliter is a unit of measurement for liquids.

One picoliter = 1×10⁻⁹ mililiters

So:

19 mL ---- x pL

1×10⁻⁹ mL ---- 1 pL

1×10⁻⁹x = 19

x = 1,9 × 10¹⁰ pL

or 19,000,000,000 pL

Answer: 1.9 × 10¹⁰ pL

Define the term inertia
n200080 [17]

Answer:

Explanation:

Enertia is an integral part of Newton's first law of motion.

It is the tendency of an object to <u>stay at rest</u> or <u>to continue moving</u> until and unless <u>any external unbalanced force</u>, (like, applied force or force of tension or frictional force ) is applied to either move it from rest or change its speed(in other words, accelerate it!!).

Example below, is of ball at rest (fig1) and if this ball is moving straight on a frictionless surface(like ice) it will keep moving!! until, we push it or pull it.

What is the primary cause of diffusion? some substances can dissolve in solvents heat added to a substance random internal motio
Nina [5.8K]

Answer:

random internal motion of atoms and molecule

Explanation:

The primary cause of diffusion is the random internal motion of atoms and molecules.

Randomness of atoms and molecules results in diffusion.

  • Diffusion is the movement of particles from a region of high concentration to that of lower concentration.
  • Substances often tend to spread out over the concentration gradient.
  • Therefore, they have this propensity to be randomized.
