THIS IS TIMED!! PLEASE HELP A student has about 250 mL of the liquid acetone. She wants to get a precise and accurate measure of the actual volume of the liquid without losing any. Which of these would be the best instrument to use. 500 mL graduated cylinder (±1mL) 100 mL graduated cylinder (±0.5mL) 250 mL beaker (±5mL) 500 mL beaker (±7mL)

500 mL graduated cylinder (±1mL)

Explanation:

Several laboratory glasswares are used in the laboratory, which serves different functions. They include: beakers, volumetric flask, Erlenmeyer flask etc. Beakers are flat-based glasswares used majorly for storing and mixing chemical solutions. Some beakers are also used to measure liquids.

However, graduated cylinders are tall flasks that has graduated markings on it, hence, it is majorly used for measuring liquids. According to this question, a student wants to get a precise and accurate measure of the actual volume of acetone liquid, which is about 250mL.

To do this, the best instrument she can use is a 500 mL graduated cylinder (±1mL). This is because the graduated cylinder holds enough space to contain the liquid and measure it with a level of accuracy better than beakers.

we need the questions , i may then you.

a electronegativity decreases beacuse the size of nucleus is bigger.
