Answer:
molarity of a solution = 1.192 M
Explanation:
- molarity [=] mol compound / L solution
∴ mass NaCl = 195 g
∴ molar mass NaCl = 58.44 g/mol
⇒ moles NaCl = (195 g)*(mol/58.44 g) = 3.34 mol
∴ Volumen solution = 2.8 L
⇒ Molarity NaCl solution = (3.34 mol)/(2.8 L) = 1.192 M
Solids have a definite,fixed shape.. So option B which is the second checkbox ☑️ is the correct answer... l hope it helped :)
I think it is the gas and the heat in it
