Densidad Del Alcohol -

“You did that without even using a formula,” Mateo whispered.

“And you’re in eleventh, crying over 0.001.” densidad del alcohol

“I’m going to fail,” he muttered, jabbing a finger at his chemistry data sheet. “My numbers are wrong. The density of alcohol is supposed to be 0.789 g/mL, but I keep getting 0.79.” “You did that without even using a formula,”

“The alcohol has microscopic air trapped inside. That air is lighter than the liquid. It’s making your volume reading wrong, but worse—it’s making your mass wrong for the space you think is full.” The density of alcohol is supposed to be 0

Elena shrugged. “Density is mass over volume. If there are air bubbles, you have less alcohol in the same space. So you measure a lower mass. Therefore, your calculated density is lower than the truth.”

She carefully tilted the pycnometer, letting the bubbles escape one by one, then topped it off. She weighed it, did the math on a napkin, and slid it back.

Elena, bored with her summer reading, peered over his elbow. “So? That’s basically the same.”
