276 grams of carbon in 23.0 moles
PH = -log [H+]
pH = -log (1.0x10^-4) = -(-4) = 4 or A
Compound: a thing that is composed of two or more separate elements, basically it is a mixture

Answer:
0.372 mol (corr. to 3 sig. fig.)
Explanation:
no. of mole of Ag₂O
= mass of Ag₂O ÷ relative atomic mass of Ag₂O
= 43.1 ÷ ( 107.9 × 2 + 16 )
≈ 0.185936151 mol
∵ Ratio of Ag:Ag₂O = 2:1
∴ no. of mole of Ag
= no. of mole of Ag₂O × 2
≈ 0.371872303 mol
= 0.372 mol (corr. to 3 sig. fig.)
