Molarity tells us ___.

Chemistry
1 answer:
Irina-Kira [14]3 years ago
7 0

Answer:

The answer is

B.how many grams of solute are dissolved in a given volume of solution.

Explanation:

Molar concentration is a measure of the concentration of a chemical species, in particular of a solute in a solution, in terms of amount of substance per unit volume of solution

M=n/v

M-molar concentration

N-moles of solute

v-liters of solution

To find the molar concentration of a solution, simply divide the total moles of solute by the total volume of the solution in liters.

Molar concentration is the same as molarity, but molarity and molality are not the same thing. They are different ways to quantify the amount of solute in a solution, and the concentration of a solution in molarity is not interchangeable with its concentration in molality.

Answer:  4.56 Joules

Explanation:-

The quantity of heat required to raise the temperature of a substance by one degree Celsius is called the specific heat capacity.

Q=m\times c\times \Delta T

Q = Heat absorbed = ?

m= mass of substance = 2.5 g

c = specific heat capacity = 0.372J/g^0C

Initial temperature  = T_i = 25.0°C

Final temperature  = T_f  = 29.9°C

Change in temperature ,\Delta T=T_f-T_i=(29.9-25.0)^0C=4.90^0C

Putting in the values, we get:

Q=2.5\times 0.372\times 4.90^0C

Q=4.56J

The heat absorbed by gallium must be 4.56 Joules

These goats are eating grass on a sunny day. What is happening to the carbon in the air around the living things on the mountain
polet [3.4K]

Answer:

both

Explanation:

Carbon in the air around the living thing is moving in and out of its lungs. The movement is occurring at the same time. This is one of the most important gaseous exchange important to life.

  • The goats takes in oxygen gas from the surrounding and releases carbon dioxide in the process.
  • But, air is actually drawn in by the goat which is a mixture of several gases.
  • Air contains carbon dioxide which is a rich source of carbon
  • With the carbon dioxide from respiratory processes, the goat ejects and breathes out this waste carbon matter.
  • Therefore, the gaseous exchange in a goat involves the movement of carbon in and out of the air.
