Astudent wants to make a 0.150 m aqueous solution of silver nitrate, agno3, and has a bottle containing 11.27 g of silver nitrate. what should be the final volume of the solution

V = 0.44 L

Explanation:

Moles is denoted by given mass divided by the molecular mass ,

Hence ,

n = w / m

n = moles ,

w = given mass ,

m = molecular mass .

From the question ,

w = 11.27 g

m ( for AgNO₃ ) =  169.87 g/mol

Hence , the moles can be calculated as -

n = w / m

n = 11.27 g / 169.87 g/mol

n = 0.066 mol

Molarity -

Molarity of a substance , is the number of moles present in a liter of solution .

M = n / V

M = molarity

V = volume of solution in liter ,

From the question ,

M = 0.150 M

n = 0.066 mol ( calculated above )

The final volume of the solution can be calculated by using the above equation ,

M = n / V  

0.150 M = 0.066 mol / V

V = 0.44 L

first one is the correct answer

the answer would be a
