If a mass of a cube were 48.0g and its volume 24.0 cm3 what would its density be

Chemistry
1 answer:
EastWind [94]3 years ago
5 0

Answer:

<h3>The answer is 2 g/cm³</h3>

Explanation:

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

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

From the question

mass = 48 g

volume = 24 cm³

We have

density =  \frac{48}{24}  \\

We have the final answer as

<h3>2 g/cm³</h3>

Hope this helps you

Consider the following intermediate reactions.
Alja [10]

2.1648 kg of CH4 will generate 119341 KJ of energy.

Explanation:

Write down the values given in the question

CH4(g) +2 O2 → CO2(g) +2 H20 (g)

ΔH1 = - 802 kJ

2 H2O(g)→2 H2O(I)

ΔH2= -88 kJ

The overall chemical reaction is

CH4 (g)+2 O2(g)→CO2(g)+2 H2O (I) ΔH2= -890 kJ

CH4 +2 O2 → CO2 +2 H20

(1mol)+(2mol)→(1mol+2mol)

Methane (CH4) = 16 gm/mol

oxygen (O2) =32 gm/mol

Here 1 mol CH4 ang 2mol of O2 gives 1mol of CO2 and 2 mol of 2 H2O

which generate 882 KJ /mol

Therefore to produce 119341 KJ of energy

119341/882 = 135.3 mol

to produce 119341 KJ of energy, 135.3 mol of CH4 and 270.6 mol of O2 will require

=135.3 *16

=2164.8 gm

=2.1648 kg of CH4

2.1648 kg of CH4 will generate 119341 KJ of energy

We must __________ forces to calculate net force if the forces are going in OPPOSITE directions.
Virty [35]

Answer:

subtract

Explanation:

To find the net force of two bodies going in opposite directions, we must subtract the forces this is because they are not additive forces.

  • The net force is the resultant force acting on a body.
  • This resultant force is the single force that will produce the same effects as all given forces.
  • When forces are directed oppositely on a body, they are subtracted from each other to find the net force.

In which are the ionic solids ranked in order of increasing melting point?
abruzzese [7]

Answer:A

Explanation:

The melting points of solids depend in the relative sizes of ions in the ionic lattice. The smaller the relative sizes of the ions, the higher the lattice energy and the stronger the lattice hence higher melting point. Comparing relative ionic sizes, fluoride ion is lesser in size than chloride ion hence NaF has a higher melting point than NaCl.
