What is the molarity of a solution of 4.50 g
Andrews [41]

Answer:

M = 0.23 M

Explanation:

Given data:

Molarity of solution = ?

Mass of NH₄Br = 4.50 g

Volume of solution = 213 mL (213 mL× 1L /1000 mL = 0.213 L)

Solution:

Molarity is used to describe the concentration of solution. It tells how many moles are dissolve in per litter of solution.

Formula:

Molarity = number of moles of solute / L of solution

Number of moles of NH₄Br:

Number of moles = mass/molar mass

Number of moles = 4.50 g / 97.94 g/mol

Number of moles = 0.05 mol

Molarity:

M = 0.05 mol/ 0.213 L

M = 0.23 M

STALIN [3.7K]

Answer:

66622.653 mi/hr

Explanation:

The average speed at which the Earth rotates around the Sun = 29.783 km/s

Also, The conversion of km to miles is shown below:

1 km = 0.621371 miles

The conversion of s to hr is shown below:

1 s = 1 / 3600 hr

So,

29.783\ km/s=\frac {29.783\times 0.621371\ miles}{\frac {1}{3600}\ hr}

Thus,

<u>The average speed at which the Earth rotates around the Sun in miles per hour =  66622.653 mi/hr</u>
