Answer:

mass of the gold nuggets = 386 grams

Explanation:

Density is the mass of a substance divided by it volume. Density compares the amount of matter in a substance to it volume. It talks about how tightly packed molecules of substance are compacted together. It is the ratio of mass per volume. The S.I unit of a density is kilogram per cubic meters. it can also be represented as gram per cubic centimeters.

Mathematically ,

density = mass/volume

mass of nugget = ?

density of the nugget = 19.3 g/cm³

volume of the nugget = 20.0 cm³

density = mass/volume

Make mass the subject of the formula

mass = density × volume

mass = 19.3 × 20

mass = 386 grams

Mass talks about how much matter a substance contain .It can be measured in grams or kilograms

Density * Volume = Mass

Now we substitute the values in.

19.3 g/cm^3 + 20 cm^3 = 386 g

Mass = 386 g

What is the ph of a 0.0055 m ha (weak acid) solution that is 8.2% ionized?
Trava [24]
Answer is: pH value of weak is 3.35.
Chemical reaction (dissociation): HA(aq) → H⁺(aq) + A⁻(aq).
c(HA) = 0.0055 M.
α = 8.2% ÷ 100% = 0.082.
[H⁺] = c(HA) · α.
[H⁺] = 0.0055 M · 0.082.
[H⁺] = 0.000451 M.
pH = -log[H⁺].
pH = -log(0.000451 M).
pH = 3.35.
pH (potential of hydrogen) is a numeric scale used to specify the acidity or basicity <span>an aqueous solution.</span>
