see the attached figure to better understand the problem

Step 1

<u>Find the number of pages printed  on an Apricot printer </u>

we know that

The speed of an Apricot printer is 8ppm

so

in 4.5 min

Carlos print

4.5*8=36 pages

step 2

<u>Find the time it takes Carlos to print the same amount of documents on a sure fire printer printer</u>

we know that

The speed on a sure fire printer is 12ppm

so

Divide the total of pages by the speed of the printer

36/12=3 minutes

therefore

<u>the answer is</u>

3 minutes

A dresser with the mirror attached is 6.28 feet tall. The difference between their heights is 1.28 feet. What are the heights of
Kobotan [32]

Answer:

Step-by-step explanation:

y = dresser height

x = mirror height

x+y=6.28

x-y = 1.28

x = 1.28+y

x+y=6.28

(1.28+y)+y=6.28

2y = 5

y = 2.5

Dresser = 2.5 ft

Dresser + Mirror = 2.5 + 1.28 = 6.28 ft

Mirror = 1.28 ft

The molar mass of AlCl3 is 133.34 g/mol. How many molecules of AlCl3 are there in 2 g?
Mnenie [13.5K]

To solve this problem, we have to apply mole-concept to this and we would need the molar mass of AlCl3.  2g of AlCl3 contains 9.034*10^21 molecules.

<h3>Number of Molecules in 2g of AlCl3</h3>

The molar mass of AlCl3 is given as 133.34g/mol

Data;

  • mass = 2g
  • molar mass = 133.34g/mol

Using the mole concept, we can equate the molar mass to the number of molecules present in the entity.

133.34g = 6.023*10^2^3

If we equate this

133.34g = 6.023*10^2^3\\2g = x molecules\\x = \frac{2*6.023*10^2^3}{133.34} \\x = 9.034*10^2^1 molecules

From the calculations above, 2g of AlCl3 contains 9.034*10^21 molecules.
