Question

perform the calculation. 0.025 l × 0.5000 mol/l × 84.314 g/mol write your answer with the correct number of significant g

Explanation:

Step1: Multiply volume and molarity

$0.025\ L\times0.5000\ mol/L = 0.0125\ mol$

Step2: Multiply moles and molar - mass

$0.0125\ mol\times84.314\ g/mol=1.053925\ g$

Step3: Determine significant figures

The least number of significant figures in the original values is 2 (in 0.025 L). So, rounding 1.053925 g to 2 significant figures gives 1.1 g.

Answer:

1.1 g
