Given:
The volume is V = 88 mL
Density, d = 9.77 g/mL
Because mass = volume * density, therefore the mass of the object is

Answer: The mass is 865.2 g or 0.865 kg
(2) a base because they accept H+ ions. NH3 is the conjugate base of NH4+.
The answer is D you correct
The empirical formula of the substance would be 
<h3>Empirical formula calculation</h3>
The constituents of the compound are as follows:
N = 54/201.6 = 26.78% = 26.78/14 = 1.91 moles
H = 15/201.6 = 7.44% = 7.44/1 = 7.44 moles
Cl = 132.6/201.6 = 65.48% = 65.48/35.5 = 1.84 moles
Divide the number of moles by the smallest"
N = 1.91/1.84 = 1
H = 7.44/1.84 = 4
Cl = 1.84/1.84 = 1
Thus, the empirical formula is
