A block of wood has a volume of 64 cm3 and a mass of 46 grams. What is the density of the block?

Chemistry
1 answer:
Rom4ik [11]3 years ago
3 0

The correct answer is 0.72 g/cm3

Explanation:

The density of a material depends on both its mass (amount of matter), which is usually provided in grams (g), and its volume (space occupied), which is provided in units such as cubic centimeters cm3. Moreover, to find how dense the material is, take the mass and divide it into the volume. The process for finding the density of the block of wood is shown below:

d = \frac{m}{v}

d = \frac{46 g}{64 cm3}

d = 0.718 g/cm3

This means the density is 0.71g/cm3 and this can be rounded to 0.72 g/cm3

What’s the mass of 2.80 mol of ca
Ludmilka [50]

Answer:

112.22 g

Explanation:

mass = no. of moles x atomic mass

From the periodic table, we can see the atomic mass of Ca is 40.078.

Therefore,

mass = 2.80 x 40.078

= 112.22g (corrected to 2 decimal places.)

Explain Wurtz reaction with an example ~​
Deffense [45]

Wurtz reaction is a special type of organic reaction involving the synthesis of aliphatic hydrocarbons from two molecules of an alkyl halide and two atoms of sodium in the presence of dry ether solution

Please bear in mind that wurtz reaction fails whenever tertiary alkyl halides are used.

An example of Wurtz reaction is given below:

2R – X + 2Na → R–R + 2Na + X−

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

Organic compounds can simply be defined as those classes of organic molecules which contain carbon atoms covalently bonded to hydrogen atoms (C-H bonds).

Below are some few general characteristics of organic compounds:

  • All organic compounds contain carbon.

  • Most of them are flammable.

  • They are all soluble in non-polar solvents

  • Most organic compounds / substances are covalently bonded molecules

Some classes of organic compounds are:

  • Alkanes
  • Alkenes
  • Alkenes

So therefore, Wurtz reaction is a special type of organic reaction involving the synthesis of aliphatic hydrocarbons from two molecules of an alkyl halide and two atoms of sodium in the presence of dry ether solution

a titration of 25.0mL of an x M hcl solution with 0.15M NaOH starts at a burette reading for NaOH of 0.20mL . Thr burette readin
VARVARA [1.3K]
Burette is a very accurate measuring instrument when adding solutions and has a measurement error of 0.05 mL. 
Small volumes of solutions can be transferred from the burette at a controllable rate. 
In this instance NaOH is in the burette.
Initial reading of NaOH is 0.20 mL 
end point is the point at which the chemical reaction reaches completion. In acid base reactions, end point is when all the H⁺ ions have reacted with OH⁻ ions. 
final reading of NaOH is 24.10 mL
to find the volume of NaOH dispensed we have to find the difference between final reading and initial reading 
volume of NaOH added = 24.10 mL - 0.20 mL = 23.90 mL
volume of NaOH dispensed is 23.90 mL
