Explanation:
Moles=mass/molar mass
moles × molar mass = mass
0.206 x 119= mass
Mass= 24. 51grams
Answer:
1 g/mL.
Explanation:
From the question given above, the following data were obtained:
Volume = 100 mL
Mass = 100 g
Density =?
Density of a substance is simply defined as the mass of the substance per unit volume of the substance. The density can be expressed mathematically as:
Density (D) = mass (m) / volume (V)
D = m / V
With the above formula, we can obtain the density of the liquid as follow:
Volume (V) = 100 mL
Mass (m) = 100 g
Density (D) =?
D = m / V
D = 100 / 100
D = 1 g/mL
Thus, the density of the liquid is 1 g/mL
(4) HBr and H2SO4 is the correct answer.
Hope this would help~
