Hey there!
Mass = ?
volume = 105 mL
Density = 2.26 g/mL
Therefore:
D = m / V
2.26 = m / 105
m = 2.26 * 105
m = 237.3 g
Hope this helps!
Dissociation, dispersion, and ionization.
Answer: D
there are 4 Al and 6 O
B. Water quality
NaHCO₃ (s) + HCl (aq) → NaCl (aq) + CO₂ (g) + H₂O (l)
From reaction coefficient: mole NaCl = mole NaHCO₃ = 0.0119
so mass NaCl:
= mol x Mr NaCl
= 0.0119 x 58.5 g/mol
= 0.696 g
