Lucite contains 59.9 g C, 8.06 g H,
Alexxandr [17]
You start by finding the mol of each

59.9g C x (mol C / 12.01 g C) = 4.98 mol C
8.06g H x (mol H / 1.00 g H) = 8.06 mol H
32.0 g O x (mol O / 16.0 g O) = 2 mol O

So when you set it up you have
C4.98 H8 O2

You divide each by the smallest mol. The smallest mol is 2

C2 H4 O2.5

However you can’t have half a mol in the empirical formula. If the value ends in 0.5, you multiply everything by 2

You’re left with

C2H8O5

The EMPIRICAL formula for lucite is C2H8O5

Note empirical is not the same as chemical formula.

An opening volumetric cylinder filled with water at volume 0.003m after period of
raketka [301]

Answer:

= - 303.975 Joules

Explanation:

Given that:

The volume of the cylinder = 0.003 m^3

Now, to liters:

The volume = 0.003 *1000 L

= 3 L

For an open cylinder, we mean the atmospheric pressure is at standard condition.

Thus, the workdone = -PΔV

= - 1 atm (3 L)

= - 3 L atm

1 L atm to Joules

= 101.325 Joules

Therefore;

=- 3* 101.325 Joules

= - 303.975 Joules
