Question

i)
urea [CO(NH2)2]
ii)
acetone [CH,COCH,
8
iii)
boric acid [H,BO3]
iv)
sulphuric acid [H,80) 22.1
1) Calculate the molar mass of the following compounds.​

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
