Question

Calculate the polarity of the following solutions.

1. 0.600 mole glucose in 0.100 L of a glucose solution

2. 73.0 g of HCl in 2.00 L of a HCl solution

3. 37.5 g of NaOH in 310. mL of a
NaOH solution

Answer 1

is it polarity or molarity?

i am assuming this a Molarity and proceeding

1. 0.600 mole glucose in 0.100 L of a glucose solution

formula for molarity

M = moles / Volume in liters

M = 0.6 mol / 0.1 L = 6 mol /L

2.

moles of HCl = mass of HCl / molar mass of HCl = 73.0 g / 36.4609 g/mol = 2 mol

volume = 2.00 L

Molarity = 2 mol / 2 L = 1 mol / L

3.

molaes of NaOH = 37.5 g / 40 g/mol = 0.9375 mol

Volume = 310 mL convert in to L = 0.31 L

Molarity = 0.9375 mol / 0.31 L = 3.024 M
