Answer:

The mass of material is 96.12 g .

Explanation:

Density:

Density is equal to the mass of substance divided by its volume.

Units:

SI unit of density is Kg/m3.

Other units are given below,

g/cm3, g/mL , kg/L

Formula:

D=m/v

D= density

m=mass

V=volume

Symbol:

The symbol used for density is called rho. It is represented by ρ. However letter D can also be used to represent the density.

Given data:

density of material = 2.7 g/mL

volume= 35.6 mL

mass= ? (in g)

Now we will put the values in the formula,

d= m/v

m=d×v

m= 2.7 g/mL × 35.6 mL

m= 96.12 g

so, the mass of material is 96.12 g .

Thepotemich [5.8K]

Answer:

Kc for this reaction is 0.43

Explanation:

This is the equilibrium:

N₂(g) + 2H₂O(g) → 2NO(g) +2H₂(g)

And we have all the concentration at equilibrium:

N₂: 0.25M

H₂ : 1.3M

NO: 0.33M

H₂: 1.2M

They are ok, because they are in MOLARITY. (mol/L)

Let's make the expression for Kc

Kc = ( [NO]² . [H₂]² ) / ([N₂] . [H₂O]²)

Kc = (0.33² . 1.2²) / (0.25 . 1.2²)

Kc = 0.4356

In two significant digits. 0.43

LenKa [72]
<span>In their mechanism of action, a difference between lipid-soluble and water-soluble hormones is that </span>lipid-soluble hormones diffuse into the cell's plasma membrane to access protein receptors, while water-soluble hormones bind to protein receptors on the plasma membrane without diffusion.

Examples of lipid-soluble hormones are steroids. Examples of water-soluble hormones are polypeptides.
