How many grams of sodium chloride

Chemistry
1 answer:
julia-pushkina [17]2 years ago
4 0

Answer:

Mass = 27.291 g

Explanation:

Given data:

Mass of sodium chloride = ?

Mass of water = 534 g

Molality = 0.875 m

Solution:

Molality:

It is the number of moles of solute into kilogram of solvent.

Formula:

Molality = number of moles of solute / kilogram solvent

Mathematical expression:

m = n/kg

Now we will convert the g into kg.

Mass of water = 534 g× 1kg/1000 g = 0.534 kg

Now we will put  the values in formula.

0.875 m = n / 0.534 kg

n = 0.467 mol

Now we will calculate the mass of sodium chloride:

Mass = number of moles × molar mass

Mass =  0.467 mol  × 58.44 g/mol

Mass = 27.291 g

How many atoms are there in 24 moles of Fe?
Semenov [28]

Answer: There are 145 \times 10^{23} atoms in 24 moles of Fe.

Explanation:

According to the mole concept, 1 mole of a substance contains 6.022 \times 10^{23} atoms.

Therefore, atoms present in 24 moles of Fe are calculated as follows.

24 mol \times 6.022 \times 10^{23} atoms/mol\\= 144.52 \times 10^{23} atoms\\or,  145 \times 10^{23} atoms

Thus, we can conclude that there are 145 \times 10^{23} atoms in 24 moles of Fe.

Describe the process of convection and how it contributes to seafloor spreading
kobusy [5.1K]

Answer:

Seafloor spreading and other tectonic activity processes are the result of mantle convection. ... Seafloor spreading occurs at divergent plate boundaries. As tectonic plates slowly move away from each other, heat from the mantle's convection currents makes the crust more plastic and less dense.
