Fortification of food with iron is done using FeSO ₄ 7 H ₂ O . The mass in grams of the FeSO ₄ 7 H ₂ O required to achieve 12 ppm of iron in 150 kg of wheat is ____ (Nearest integer) [Given : Molar mass of Fe , S and O respectively are 56,32 and 16 ~g ~mol ⁻¹ ]

Correct answer

0

Step-by-step solution

aligned & Let mass of iron = wg & w 150 10^3 10^6=12 & w =150 12 10⁻³=1.8 gm aligned Let mass of FeSO ₄ 7 H ₂ O = w ₁ gm aligned & Moles of Fe = 1.8 56 = ( w ₁ 56+96+7 18 ) & w ₁=8.935 gm aligned
