HELP PLZ, GIVING BRAINLIEST!!
Which is more concentrated, 25g NaCl dissolved in 500mL of water or a 10% solution of NaCl (percent by mass)? Show work, please.

Explanation:

25g in NaCl dissolved in 500 ml of water

M(NaCl) = 58,44 g/mol

n1(NaCl) = m(NaCl) / M(NaCl)

n1(NaCl) = 25 / 58,44

n1(NaCl) = 0,428 mol

C1 = n1(NaCl) / V

C1 = 0,428 / 0,500

C1 = 0.856 mol/L

10% solution of NaCl

10% solution of NaCl means 10 g of NaCl for 100g of water

therefore : 50 g of NaCl for 500 g of water (1,00L)

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.

0.88m hope i am correct : )
