Find the mass of 175.4mL of benzene if the density is 0.8786g/ml
bulgar [2K]
Hey there!:

Volume = 175.4 mL

density = 0.8786 g/mL  

mass = ?

Therefore:

D = m / V

0.8786 = m / 175.4

m = 0.8786 * 175.4

m = 154.10644 g

hope this helps!

Answer:

This question is incomplete; the complete part/options is:

A) They are precise, but not accurate.

B) They are accurate, but not precise.

C) They are both accurate and precise.

D) They are neither accurate nor precise

The answer is C.

Explanation:

Accuracy refers to how close a series of measurements is to a known or true value while precision is the closeness of the measurements to one another.

The known concentration of a solution is 2.0M. In an experiment which Susan conducts five times and gets a solution concentration of 1.9M, 2.1M, 1.8M, 1.9M, and 2.2M respectively.

Based on these measured solute concentrations, one would observe that the measured values of: 1.9M, 2.1M, 1.8M, 1.9M, 2.2M are close to one another. This means that the measurements are PRECISE.

Also, the measured values are not too distant from the known value of 2.0M, hence, it can be said that the measurements are ACCURATE.

Therefore, Susan's measurements of the solute concentration are both accurate and precise.
