The minimum number of boxes of pencils to be ordered is 630 boxes.

Explanation:

Since a pupil uses averagely 9.3 pencils

and a box contains 12 pencils,

the school enrollment is also 812

school's enrollment x average use of pencil per student

__________________________________________

            number of pencils in a box

A sample containing 16.93 metal pellets is poured into a graduated cylinder containing 11.2 of water, causing the water level in
mixer [17]

Answer:

<h3>The answer is 1.99 g/mL</h3>

Explanation:

The density of a substance can be found by using the formula

density =  \frac{mass}{volume} \\

From the question

mass = 16.93 g

volume = final volume of water - initial volume of water

volume = 19.7 - 11.2 = 8.5 mL

We have

density =  \frac{16.93}{8.5}  \\  = 1.9917647058...

We have the final answer as

<h3>1.99 g/mL</h3>

Hope this helps you

<h3>What are organic compounds?</h3>

Organic compounds are compounds which contains carbon and hydrogen

Some few classes or organic compounds or hydrocarbons are as follows:

  • Alkanes
  • Alkenes
  • Alkynes
  • Alkanols
  • Alkanoic acid
  • Ketones
  • Esters

So therefore, the group of unsaturated hydrocarbons which 2 carbons are double bonded together, with H bonded to the left, and C H 2 bonded below left, above right, and below right is derived from <u>Alkenes</u>
