Which is more concentrated with respect to sodium ions, 50.0 g of nacl dissolved in 500.0 ml of solution or 59.0 g of na2so4 in 500.0 ml of solution? a they are equal in concentration b the nacl solution described c the na2so4 solution described question 12 (1 point) what percentage of sodium sulfate molecules are separated when placed in water? a 50% b 100% c 10% d 80%

b) The NaCl solution described

Explanation:

First we calculate the number of moles for each compound:

moles = mass / molecular weight

moles of NaCl = 50 / 58.5 = 0.854 moles

moles of Na₂SO₄ = 59 / 142 = 0.415 moles

In the first solution we have:

0.854 moles of NaCl which means that 0.854 moles of sodium Na⁺ ions are dissolved in 500 mL of solution

In the second solution we have:

0.415 moles of Na₂SO₄ which means that 0.843 moles of sodium Na⁺ ions are dissolved in 500 mL of solution

Now we may conclude that the NaCl is more concentrated than the Na₂SO₄ solution.

they are both synthetic elements

explanation:

d

the earth would become to overheated and everything alive on it will eventually die from overheating. plants will eventually die as well, water will evaporate, and it will be nothing but a hot planet without anything living on it.
