How many moles of NaOH are present in 18.5 ml of 0.130 M NaOH?

1 Answer

Answer:

We can solve this by the unitary method.

Explanation:

0.130 moles are present in 1000 mL (1L) of solution.

#color(white)(wwwwww# #"1000 mL = 0.130 moles"#
#color(white)(wwwiwwwww# #"1 mL" = 0.130/1000 " moles"#
#color(white)(wiwwwww# #"18.5 mL" = 0.130/1000 xx 18.5" moles"#
#color(white)(wwwwwwwwwww# # = 13 xx 18.5 xx 10^(-5) " moles"#
#color(white)(wwwwwwwwwww# # = 2.41 xx 10^(-3) " moles"#

I hope you got this!
