How many molecules are contained in 0.254 moles of diarsenic trioxide

1.53 × 10²³ molecules As₂O₃

Explanation:

Step 1: Define

Diarsenic Trioxide - As₂O₃

Avagadro's number: 6.02 × 10²³ atoms, molecules, formula units, etc.

Step 2: Use Dimensional Analysis

= 1.52908 × 10²³ molecules As₂O₃

Step 3: Simplify

We have 3 sig figs.

1.52908 × 10²³ molecules As₂O₃ ≈ 1.53 × 10²³ molecules As₂O₃

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.

i would say b

explanation:

but i think i would need more information than that
