Answer:

The correct answer is supergiant.  

Explanation:  

The largest stars in the universe are known as the supergiant stars. They can be thousands of times larger in comparison to the Sun and exhibits a mass of up to 100 times greater. The supergiants come in an array of temperatures and sizes, however, they are usually categorized as being either blue or red.  

The red supergiants exhibit a mass of about 8 times more than the Sun, and are usually old stars, which were once identical in size to the Sun. On the other hand, the blue supergiants are hotter in comparison to the red supergiants, however, are much smaller in size.

Which solution has the lowest freezing point?
Leokris [45]
<span>Correct Answer: Option 3 i.e. 30 g of KI dissolved in 100 g of water.

Reason:
Depression in freezing point is a colligative property and it is directly proportional to molality of solution.

Molality of solution is mathematically expressed as,
Molality = </span>\frac{\text{Number of moles}}{\text{Weight of solvent (Kg)}}<span>

In case of option 1 and 2, molality of solution is 0.602 m. For option 3, molality of solution is 1.807 m, while in case of option 4, molality of solution is 1.205 m.

<u><em>Thus, second solution (option 2) has highest concentration (in terms of molality). Hence, it will have lowest freezing point</em></u></span>

What is the mass of 4.38 x 10^24 formula units of sodium chloride (NaCl)?
lana66690 [7]

Answer:

Mass = 427.05 g

Explanation:

Given data:

Formula units of sodium chloride = 4.38 ×10²⁴

Mass of NaCl = ?

Solution:

One mole contain formula units = 6.022 ×10²³

4.38×10²⁴ formula units × 1mol /6.022 ×10²³ formula units

0.73 ×10¹ mol

7.3 mol

Mass of NaCl:

Mass = number of moles × molar mass

Mass = 7.3 mol × 58.5 g/mol

Mass = 427.05 g
