sebanyak 4 gram natrium hidroksida Dilarutkan dalam 1000 ml larutan air berapa Molaritas larutan tsb

M = gr/ Mr × 1000/V

gr = 4
Mr NaOH = 40
V = 1000

M = 4/ 40 × 1000/1000
    = 1/10
M = 0,1

dik : 4 gr

Mr NaOH = Ar Na + O + H
(23+16+1) = 40

1000 ml

jawab :
M = gr / Mr × 1000 / v
M = 4 / 40 × 1000 / 1000
M = 0,1

maaf kalau salah
