Question

Calculate the total number of moles present in 196 g of H2So4

Answer 1

gram molecular mass of H2SO4 = 1*2+32+16*4 = 2 + 32 + 64 = 98. no. of moles of 98g of H2SO4 = 1 mole So, total no. of moles of 196 g of H2SO4 is 2 mole. Please mark me as brainliest and thank you for asking this question mole concept is my favorite topic of whole chemistry

Answer 2

You have to get the relative atomic mass of sulphuric acid and after you divide the mass given by the calculated rfm so that you get the number of moles. Hope it helps you.
