Conversion factor is defined as the ratio which shows the relation between two different units. It is equal to one.

Since, one litre is equal to thousand millilitre.

Expression is : 1 L = 1000 mL

The given value of measurement is 400.08 mL

Convert the above measurement in L, we get

400.08 mL = \frac{400.08}{1000} L

= 0.40008 L.

Now, in given measurement, there are five significant figures, thus, the above number must be written in five significant figures i.e 0.40008 L.

Hence, the answer is 0.40008 L.

A photocopier is making reduced copies of a photo that measures 25 centimeters in height. The height of the first copy is​ 80% o
Marat540 [252]

Answer:The height of First Copy is 20 cm.

Step-by-step explanation:

Given:

Original Height = 25 cm

First copy is reduce to 80% of Original height.

Therefore to find the height of first copy can be find out by multiplying 80 with original height and then dividing by 100.

∴ Height of First Copy =

Hence Height of first copy is 20 cm

Now Another copy is reduce to 85% of First Copy.

Therefore to find the height of another copy can be find out by multiplying 85 with first copy height and then dividing by 100.

∴ Height of Another Copy =

Hence Height of Another copy is 17 cm

Calculate the value of ΔG°, ΔH°, &amp; ΔS° for the oxidation of solid elemental sulfur to gaseous sulfur trioxide at at 25°C.​2S
Liula [17]

Answer:

ΔG° = -750324.96 J/mol = -750.324 Kj/mol

ΔH° = - 790.4 kJ/mol = -790400 j/mol

ΔS° =  = - 134.48 J K-1mol-1

Explanation:

(S, rhombic) + 3O2( g) → 2SO3 (g)

Temperature = 25°C + 273 = 298K (Converting to kelvin temperature.)

The formulae relating all four paramenters (ΔG°, T, ΔH°, & ΔS°) is given as;

ΔG° = ΔH° - TΔS°

All H and S values used are measurements at 25°C

Calculating ΔH

You started with 1 mole of Sulphur and 3 moles of oxygen.

Total starting enthalpy = 0+ 3(0) = 0 kJ/mol

You ended up with 2 moles of SO3.

Total enthalpy at the end = 2(-395.2) = - 790.4 kJ/mol

enthalpy change = what you end up with - what you started with.

ΔH = enthalpy change =  - 790.4 kJ/mol - 0 kJ/mol = - 790.4 kJ/mol = -790400 j/mol

Calculating ΔS

You started with 1 mole of Sulphur and 3 moles of oxygen.

Total starting entropy =31.88 + 3(205) = 646.88 J K-1mol-1

You ended up with 2 moles of SO3.

Total entropy  at the end = 2(256.2) = 512.4 J K-1mol-1

entropy change = what you end up with - what you started with.

ΔS = entropy change =  512.4 J K-1mol-1 - 646.88 J K-1mol-1

= - 134.48 J K-1mol-1

Inputing the values into the formular, we have;

ΔG° = ΔH° - TΔS°

ΔG° = - 790400 - 298 (- 134.48)

ΔG° =  - 790400 + 40075.04

ΔG° = -750324.96 J/mol = -750.324 Kj/mol
