atom is the smallest unit of an element that can or cannot exist freely. While on the other hand, a molecule is a set of atoms that are held together with the help of a bond and is the smallest unit of a compound. Furthermore, an atom can or cannot exist in a free state.

A truck initially traveling at 20m/s decelerated at 1.50m/s2. Find (a) how long it takes to stop (b) how far it moves in that ti

finlep [7]

vf² = vi² + 2ad

vf = vi +at

vf = final velocity

vi = initial velocity

decelerated = a = - (negative)

a. stop ⇒ vf = 0

vf = vi+at

0 = 20 - 1.5t

1.5t=20

t = 13.3 s

b. vi = 20 m/s

0 = 20² - 1.5d

1.5d = 20²

1.5d = 400

d =266.67 m

c. d = vi.t -1/2at²

d = 20.3 - 1/2.1.5.3²

d = 53.25 m

How many 50 mg tablets can be produced from 10 kg of ibuprofen?

miv72 [106K]

Answer:

2 × 10⁵

Explanation:

The total mass of the drug, ibuprofen = 10 kg

Kilograms and grams are related as:

1 kg = 1000 g

Also,

Grams and milligrams are related as:

1 g = 1000 mg

So,

1 kg = 10⁶ g

Mass of the drug, ibuprofen = 10 × 10⁶ mg = 10⁷ mg

Given, mass of tablet = 50 mg

So, number of tablets = total mass / Mass of 1 tablet = 10⁷ mg / 50 mg = 2 × 10⁵

<u>Number of 50 mg tablets = 2 × 10⁵</u>
