Answer 1

Answer #1

Molarity is given by the formula,

Molarity = moles of solute/volume of solution in liters.

Number of moles = Mass/molar mass

Molar mass of FeBr3 = 295.56 g/mol

Moles of FeBr3 = 200/295.56

= 0.677 moles

Volume = 0.677 mol × 1.3 M

0.8801 liters

1 litre = 1000 millilitres

Volume = 880.1 ml

Answer in 2 significant figures = 880 ml

Rules for significant figures :- 1. All non-zero digits are significant. 2. If any zeroes occurs between two significant digi
