Question

calculate the molecular no.of 26g NaOh
​

Answer 1

Answer:

Number of moles can be calculayed by using the formula, n(no. of moles)= given mass of the substance ÷ molar mass of the substance

So in this case,

You must first find the molar mass of NaOH

Molar mass of NaOH = 23 + 16 + 1 = 40 g/mol

Using the above mentioned formula,

Number of moles in 60 grams of MaOH is

n= 60/40 = 1.5 moles of NaOH

To practice more problems on mole concept i would

recommend you to buy ‘Modern Approach To Chemical Calculations’ by RC Mukerjee. This book has helped me a lot.

I think this is the answer for your question

hope this helps u...:)
