Deter- mine how many moles of vitamin a2 contain the same number of atoms as 1.000 mol vitamin a.

1.041 mol

Explanation:

1.000 mol of vitamin A (C₂₀H₃₀O) has 20 + 30 + 1 = 51 moles of atoms. The moles of atoms in 1.000 mol of vitamin A are:

1.000 mol Vit A × (51 mol Atoms/ 1 mol Vit A) = 51.00 mol Atoms

If vitamin A2 has the same number of atoms, it also has the same number of moles of atoms, that is, 51.00 moles of atoms.

1 mol of vitamin A2 (C₂₀H₂₈O) has 20 + 28 + 1 = 49 moles of atoms. The moles of vitamin A2 that contains 51.00 moles of atoms are:

51.00 mol Atoms × (1 mol Vit A2/49 mol Atoms) = 1.041 mol Vit A2

answer: e.   sour taste

explanation: acids are those substances which dissociates in water to give ions. as they dissociate to give ions, they act as electrolytes and thus are electrically conductive. acids are sour in taste. example: hcl

bases are those substances which dissociates in water to give ions or accepts ions. as they dissociate to give ions, they act as electrolytes and thus are electrically conductive. bases are bitter in taste. bases are slippery in nature.
