Calculate the ph for a 0.3 m solution of (a) sodium leucinate

1 answer:

5 0

To get the pH value for a certain aqueous solution, the concentration of the hydronium ions (in moles per liter) should be know. This concentration is also known as the "molarity".
pH = -log [H3O+]

We are given that the molarity = 0.3 m
Therefore,
pH = -log[0.3] = 0.5228787

What is the density of this problem

Luda [366]

Answer:

Density of copper = 8.9 g/cm³

The density of liquid mercury is 13.6 g/cm³ which means mercury is denser than copper so copper will float on liquid mercury.

Explanation:

Given data:

weight of copper metal = 1896 g

Dimensions of block = 8.4 cm, 5.5 cm, 4.6 cm

Density of copper = ?

Will it float to the liquid mercury = ?

Solution:

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

volume of coper metal = 8.4 cm × 5.5 cm × 4.6 cm

volume of coper metal =212.52 cm³

d = 1896 g/ 212.52 cm³

d = 8.9 g/cm³

The density of liquid mercury is 13.6 g/cm³ which means mercury is denser than copper so copper will float on liquid mercury.
