A 7.06% aqueous solution of sodium bicarbonate has a density of 1.19g/mL at 25°C what is the molarity and molality of the soluti

lilavasa [31]

c = 1.14 mol/L; b = 1.03 mol/kg

Molar concentration

Assume you have 1 L solution.

Mass of solution = 1000 mL solution × (1.19 g solution/1 mL solution)

= 1190 g solution

Mass of NaHCO3 = 1190 g solution × (7.06 g NaHCO3/100 g solution)

= 84.01 g NaHCO3

Moles NaHCO3 = 84.01 g NaHCO3 × (1 mol NaHCO3/74.01 g NaHCO3)

= 1.14 mol NaHCO3

c = 1.14 mol/1 L = 1.14 mol/L

Molal concentration

Mass of water = 1190 g – 84.01 g = 1106 g = 1.106 kg

b = 1.14 mol/1.106 kg = 1.03 mol/kg

How does examining past data help prepare people for feature weather hazards?

klemol [59]

Answer:

It lets people prepare for future weather hazards:

- If, in certain months and on certain dates, the past data shows that there's a history of rain or heat stroke on those days, people can prepare in the future for those events.

- They can also expect wind speeds, temperatures and stuff like that!

Which variable increases when potential energy increases?

beks73 [17]

Answer:

Height and mass

Explanation:

The potential energy of a body is the energy due to the position of a body.

It is mathematically expressed as:

Potential energy = m g h

m is the mass of the body

g is the acceleration due to gravity

h is the height of the body

Acceleration due to gravity on the earth surface is a constant.

As mass and height of a body increases, the acceleration due to gravity will also increase.

zloy xaker [14]

Answer: The mass of morphine is 0.059 grams

Explanation:

To calculate the number of moles for given molarity, we use the equation:

$\text{Molarity of the solution}=\frac{\text{Moles of solute}\times 1000}{\text{Volume of solution (in mL)}}$

Molarity of sulfuric acid solution = 0.0116 M

Volume of solution = 8.92 mL

Putting values in above equation, we get:

$0.0166M=\frac{\text{Moles of sulfuric acid}\times 1000}{8.92}\\\\\text{Moles of sulfuric acid}=\frac{0.0116\times 8.92}{1000}=1.035\times 10^{-4}mol$
