Answer:
0.052L
Explanation:
Molarity of a substance, which refers to the molar concentration, is calculated as follows:
Molarity (M) = number of moles (mol) ÷ volume (L)
Mole = mass ÷ molar mass
Molar Mass of AgNO3 since Ag = 108, N = 14, O = 16
108 + 14 + 16(3)
= 108 + 14 + 48
= 170g/mol
Mole = 21.89 g ÷ 170g/mol
Mole = 0.129moles
Using Molarity (M) = number of moles (mol) ÷ volume (L)
Volume = number of moles ÷ molarity
V = 0.129 ÷ 2.50
V = 0.0516
To the correct significant figure i.e. 4s.f, the numerical value of volume = 0.052L
