A 0.266-g sample of NaC1 (molar mass = 58.44 g/mol) is dissolved in enough water to make 5.20 mL of
solution. Calculate the molarity of the resulting solution.
O 0.875 M
O 4.55 x 10-3 M
O 0.987 M
O 1.14 M
O 0.731 M

Respuesta :

0.266g / 58.44g/mol= 0.00455mol
M= moles / volume (L)
0.00455mol / .0052L
M= 0.875
