If 200.00 mL of a solution of sugar and water contains 0.0025 moles of sugar, what is the concentration of the solution in units of moles per unit volume? Round decimals to the nearest thousandth where applicable. Do not include trailing zeros in decimal answers (e. g., 0.05 instead of 0.050).

0.013 mol/L

Explanation:

Molarity, which is molar concentration or moles per unit volume, can be calculated using the formula:

M = n/V

Where; M = Molar concentration of solution

n = number of moles of solute

V = Volume of solvent

n = 0.0025 moles of sugar

V = 200.00mL of solution

Since 0.001L = 1mL

200mL = 0.200L

Therefore, M = n/V

M = 0.0025/0.200

M = 0.0125 mol/L

Round up to the nearest thousandth ~ 0.013mol/L

1. they vary with a higher number because boiling is way hotter than melting
