My Everest is the highest mountain on earth.its height is 8.848 km. Convert this height to feet. Write your answer in standard n
Vinvika [58]

Answer: 2.9(10)^{7} ft

Explanation:

Firstly we need to know that 1 km=3280.84 ft, then we cam make the conversion:

8848 km \frac{3280.84 ft}{1 km}=29,028,872.32 ft This is the height of Mount Everest in feet

However, we can express it using scientific notation by counting to the left the decimal spaces:

29,028,872.32 ft \approx 2.9(10)^{7} ft

Calculate the molality of 75.0 grams of MgCl2 (molar mass=95.21 g/mol) dissolved in 500.0 g of solvent.
nordsb [41]

<u>Answer:</u> The molality of magnesium chloride is 1.58 m

<u>Explanation:</u>

To calculate the molality of solution, we use the equation:

\text{Molality}=\frac{m_{solute}\times 1000}{M_{solute}\times W_{solvent}\text{ (in grams)}}

Where,

m_{solute} = Given mass of solute (magnesium chloride) = 75.0

M_{solute} = Molar mass of solute (magnesium chloride) = 95.21 g/mol  

W_{solvent} = Mass of solvent = 500.0 g

Putting values in above equation, we get:

\text{Molality of }MgCl_2=\frac{75.0\times 1000}{95.21\times 500.0}\\\\\text{Molality of }MgCl_2=1.58m

Hence, the molality of magnesium chloride is 1.58 m
