To find the number of molecules in 49 g of H2SO4, first calculate the molar mass of H2SO4 which is 98 g/mol. Next, use Avogadro's number (6.022 x 10^23) to convert grams to molecules. This gives you approximately 3 x 10^23 molecules in 49g of H2SO4.

In one cup of wild rose hips (northern plane Indians), there are 49g of carbohydrates. (63% of that is dietary fiber).
The weight of a 100mL round bottom flask can vary depending on the material it is made of. A typical 100mL glass round bottom flask weighs approximately 100-150 grams.
The volume of a wooden yo-yo can vary depending on its size and shape, but it is typically around 50-100 cubic centimeters. The mass of a wooden yo-yo is usually between 20-50 grams.

1 M solution of H2SO4 is concentrated than 1 N because Molarity is no. of moles dissolved per Litre of the solution here i.e 98 g of H2SO4 dissolved per litre. Normality is Gram equvalent weight (no. of electron lost or gained in chemical reaction or acidty or basisty) dissolved per litre. equvalent weight of H2SO4 is 98/2= 49 mean 1 N of H2SO4 is 49g dissolved per litre.

Equivalent Weight is an archaic name for 'Moles'. Moles = mass(g) / Mr ( Relative molecular mass). or Ar (Relative Atomic mass). If we take the reaction of sulphuric acid and sodium hydroxide. First write down the BALANCED reaction eq'n. H2SO4 + 2NaOH = Na2SO4 + 2H2O Notice the molar ratios are 1:2::1:2 So if we have 49g (H2SO4) , how much , by mass of sodium hydroxide, do we need to neutralise the acid. ? This mass of sodium hydroxide is the Equivalent Weight. First calculate the Mr(H2SO4) from atomic masses on the Periodic Table. 2 x H = 2 x 1 = 2 1 x S = 1 x 32 = 32 4 x O = 4 x 16 = 64 2 + 32 + 64 = 98 So moles(H2SO4) = 49g / 98 = 0.5 mole. By molar ratios above 1 mole reacts with 2 moles Hence 0.5 moles reacts with 1 mole. So we need 1 mole(NaOH) Again calculate the Mr(NaOH) 1 x Na = 1 x 23 = 23 1 x O = 1 x 16 = 16 1 x H = 1 x 1 = 1 23 + 16 + 1 = 40 Using the moles equation again moles = mass( g)/Mr Algebraically rearranging mass(g) = moles X Mr Mass(NaOH) = 1 moles X 40 = mass(NaOh) = 40 g ( The 'Equivalent Weight). This is the mass required to neutralise 49 g of sulphuric acid.
