Answer:

We Can deduce terrestrial and gaseous planets with varying acceleration due to gravity.

Explanation:

Looking at the chart, what seems to be is 7 planets whos acceleration due to gravity intern's of m/s is given. In which Mercury the fastest spinning planet has an acceleration velocity of 3.7 similar to that of mars that is the lowest in all of them.

Saturn and Neptune being gas giants are having a similar mass of 11.0 (m/s) due to there magnetic cores and heavy and dense gases of helium and hydrogen atoms.

Others like the venus and Uranus and Jupiter have varying acceleration as Jupiter is the second densest gaseous planet having layers of atmospheric turbulence and thus having 25.9 m/s square acceleration. While all the top three planets are terrestrial and rest four are gaseous giants. Lacking rocky structure but having extreme atmospheric motion.

Sample A: 300 mL of 1M sodium chloride

yarga [219]

Answer:

sample B contains the larger density

Explanation:

Given;

volume of sample A, V = 300 mL = 0.3 L

Molarity of sample A, C = 1 M

volume of sample B, V = 145 mL = 0.145 L

Molarity of sample B, C = 1.5 M

molecular mass of sodium chloride, Nacl = 23 + 35.5 = 58.5 g/mol

Molarity is given as;

$C = \frac{moles \ of \ solute, \ mol}{liters \ of \ solvent} \\\\Moles \ of \ solute \ for \ sample \ A = 1 \times 0.3 = 0.3 \ mol\\\\Moles \ of \ solute \ for \ sample \ B = 1.5 \times 0.145 = 0.2175 \ mol$
