Density=mass/volume

Density=18.4g/11.2ml

Density=1.64

Just make sure you include the unit of measurement with your answer.

Answer:

Density of the object, \rho=1.64\ g/mL

Explanation:

It is given that,

Mass of the object, m = 18.4 g

Volume of the object, V=11.2\ mL

We need to find the density of the object. The density of a material is given by total mass divided by total occupied volume. Its formula is given by :

d=\dfrac{m}{V}

d=\dfrac{18.4\ g}{11.2\ mL}

d=1.64\ g/mL

So, the density of the object is 1.64\ g/mL. Hence, this is the required solution.

Montano1993 [528]

Answer:

C

Explanation:

Since Moles=mass/molar mass

Mass=432g

Molar mass=261g/mol

Moles=1.65mol

The initial pressure of a mixture of C6H6 and an excess of H2 in a rigid vessel is 1.21 atm. A catalyst is introduced. After the
KengaRu [80]

Answer:

mole fraction of C6H6 = 0.613 atm

Explanation:

The equation for this reaction is :

          C_6H_6 _{(g)} + 3H_2_{(g)} \to C_6H_{12}_{(g)}

Initial      P₁            P₂             0

Final        0           P₂ -P₁/2      P₁

After completion of the reaction;

P₁  +  P₂  = 1.21 atm                    ----- (1)

P₂  -  P₁/2 +  P₁ = 0.839 atm

P₂ + P₁/2 = 0.839 atm          ----- (2)

Subtracting (2) from (1); we have:

P₁/2 = 0.371

P₁ = 0.742 atm

From(1)

P₁  +  P₂  = 1.21 atm

0.742 atm + P₂  = 1.21 atm

P₂  = 1.21 atm - 0.742 atm

P₂  = 0.468 atm

Thus, the partial pressure of C6H6 = 0.742 atm

∴

Partial pressure = Total pressure × mole fraction of C6H6

mole fraction of C6H6 = Partial pressure /  Total pressure

mole fraction of C6H6 = 0.742 atm / 1.21 atm

mole fraction of C6H6 = 0.613 atm

What happens if a chemical and physical change combine together?
sweet-ann [11.9K]

In a chemical change, a new substance is made, like when you burn a candle. In a physical change, no new substance is made, like when water turns to ice.
