Question

calculate the number of moles in 80g of NaoH. The molecular mass of NaoH is 40g​

Answer 1

Answer:

Hᴇʏ ᴍᴀᴛᴇ !!

Number of moles can be calculated 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

No. of moles in 40g

NaOH n = 40/40 = 1 moles
