Question

Calculate molarity of 4g caustic soda when dissolved I 200 ml of solution

Answer 1

Answer:

the answer is 0.08M

Explanation:

we jave NaOH 4g so, it is givenass we have.

now we know that NaOH os 40g on weight so we find no. of moles as 4/40=0.1

ans volm. is 1200ml so in litres we have 1.2 litres of volm. so

molarity =no. of moles/ volm. in lit

so 0.1/1.2=0.08 M solution

Hope it helped
