Your answer should indicate the proper precision (correct number of insignificant figures).

1. 1,010 L
2. 1,007.0 L
3. 1,007 L
4. 1,000 L

Answers

Answer:

The sum of given measurements is 1007 L.

Explanation:

The given measurements are 28 L, 42 L, 6 L, and 931 L.

We need to find the total of these measurements.

Total = 28 L + 42 L + 6 L + 931 L

It can be written as

Total = ( 28 +42+6+931)

One simplification we get Total = 1007 L

What NaClNaCl concentration results when 259 mL259 mL of a 0.850 M0.850 M NaClNaCl solution is mixed with 567 mL567 mL of a 0.240 M0.240 M NaClNaCl solution?

Answers

Answer:

0.431M

Explanation:

To find the concentration of NaCl we need to know how many moles comes from each solution. Then, we need to sum the total volume in liters and, as molarity (Unit of concentration) is the ratio between moles and volume we can determine concentration.

Moles from first solution:

259mL = 0.259L * (0.850mol / L) = 0.22015 moles of NaCl

Moles from second solution:

567mL = 0.567L * (0.240mol / L) = 0.13608 moles of NaCl

Total moles:

0.22015 + 0.13608 = 0.35623 moles of NaCl

Total volume:

259mL + 567mL = 826mL = 0.826L

Thus, molarity of the mixture is:

0.3562 moles NaCl / 0.826

0.431M

How were the ideas of Aristotle and Democritus similar to the alchemists'?

Answers

Answer:

The ideas of Aristotle and Democritus were on a similar basis to the alchemists.

Explanation:

Aristotle believed that all matter was made from four elements: earth, air, fire, and water. Democritus was the first person to realize that if something was cut in half continuously it can never be broken down completely. Democritus called the units that could not be broken down atoms. Early alchemists believed and based their works on the notion that atoms could be rearranged into making new elements. All three of their ideas more or less work with atoms and elements.
