Question

Calculate the molar mass of the following compounds.
i) urea [CO(NH2)2] ii) acetone [CH3COCH3]
iii) boric acid [H3BO3] iv) sulphuric acid [H2SO4]

Answer 1

Answer:

urea [CO(NH2)2] Atomic mass of C =12 Atomic mass of O =16 Atomic mass of 2(N) = 28 Atomic mass of 4(H) = 4 ∴ Molar mass of Urea = 60 2. acetone [CH3COCH3] Atomic mass of 3(C) = 36 Atomic mass of 1(0) = 16 Atomic mass of 6(H) = 6 ∴ Molar mass of Acetone = 58 3. boric acid [H3BO3] Atomic mass of B = 10 Atomic mass of 3(H) = 3 Atomic mass of 3(O) = 48 ∴ Molar mass of Boric acid = 61 4. sulphuric acid [H3SO4 ] Atomic mass of 2(H) = 2 Atomic mass of 1(S) = 32 Atomic mass of 4(O) = 64 ∴ Molar mass of Sulphuric acid = 98Read more on Sarthaks.com - https://www.sarthaks.com/914332/calculate-the-molar-mass-of-the-following-compounds-1-urea-co-nh2-2-2-acetone-ch3coch3?show=914333#a914333
