Question

8 g naoh को 1 लीटर विलयन में घोला जाता है इसकी मोलरता है

Answer 1

Answer:

M=number of moles/volume in litre

Molarity on NaOH is 0.2M

Explanation:

Given Mass of NaOH is 8g

Molar mass of NaOH is 40

so moles =given Mass /molar mass

moles =8/40

moles =0.2 mol

given volume =1 litre

so,

Molarity =moles/volume in litre

Molarity= 0.2/1

Molarity is 0.2M
