Answer:
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
The mass is the density x mass, 8.908 x 17.45 = 155.4446 g
