Answer:

M1 = 6.0M

V1 = 8.33mL

M2 = 1.0M

V2 = 50.0mL

Explanation:

It is possible to find the volume that we need to prepare a diluted solution from a stock using the equation:

M1V1 = M2V2

<em>Where M is molar concentration and V volume of 1, stock solution and 2, diluted solution.</em>

Replacing:

M1 = 6.0M

V1 = Our incognite

M2 = 1.0M

V2 = 50.0mL

6.0M*V1 = 1.0M*50.0mL

V1 = 1.0M * 50.0mL / 6.0M

V1 = 8.33mL of the stock solution are needed

Which property of table salt is also a property of other ionic compounds
Svet_ta [14]
Most likely it’s crystalline structure, which makes it small granules that are soluble in water. Most, if not all, ionic compounds are salts. And salts dissolve in water.

Hope that’s correct

The heat capacity of liquid water is 4.18 J/g·°C and the heat of vaporization is 40.7 kJ/mol. How many kilojoules of heat must b
pychu [463]

Answer:

The correct answer would be - 2.4KJ or, 2400J

Explanation:

Given:

heat capacity of liquid water - 4.18 J/g·°C

heat of vaporization - 40.7 kJ/mol

Mass of water = 1g

Moles of water = mass/molar mass

= 1g/18.016g

= 0.055 moles

Then,

Total heat required = q1(to raise the temperature to 100) + q2(change from the liquid phase to gas/steam)

= m *s*dt + moles * heat of vaporization

= (1g * 4.18 j/gc * (100-67)) + 0.055* 40.7 KJ

= 137.94J + 2.26KJ

=0.138KJ + 2.26KJ

=2.4KJ or, 2400J

Thus, the correct answer would be - 2.4KJ or, 2400J

The atomic mass of potassium is 39.1. What is the mass of 6.02 × 1023 atoms of potassium? . . A.. 39.1 mg. . . . . B.. 39.1 g. .
Sholpan [36]
Atomic mass of Potassium = Mass of 1 atom of Potassium = 39.1 amu
Then
Mass of 6.02 x 1023 atoms of potassium = 39.1 x 6.02 x 1023 amu
                                                                  = 
We already know that
1 mole = 6.02 x 1023 atoms
Also
Number of mole = mass in grams/ atomic mass
Then
Mass in gram = Number of mole x atomic mass
                       = (39.1 x 6.02 x 1023)/(6.02 x 1023)
                       = 39.1 g
The correct option among all the options that are given in the question is the third option or option "B".
