An unknown liquid has a mass of 4.25 × 108 mg and a volume of 0.250 m3. what is the density of the liquid in units of g/ml?

Density is calculated as mass divided by volume.
Step one:
Convert m³ to ml.
1 m³ = 1,000,000 ml
0.250 m³ x 1,000,000 = 250,000 ml
Step two: Convert mg to g.
1 mg = 0.001 g, hence 4.25 x 10^8 mg equals 0.459 g.
Consequently, the density comes out to be 0.459 g/250,000 = 1.836 x 10^-6 g/ml.

The density of the liquid measured in g/ml is $1.836 \times 10^{-6} g / \mathrm{ml}$

Clarification:

The density is defined as the mass of the liquid divided by its volume.

Density = $\frac{\text { Mass }}{\text { Volume }}$

Given Mass = 4.25 x 10^8 mg

= 459 mg

= 0.459 g

Volume = $0.250 m^{3}$

<pTherefore, the density = $\frac{0.459}{0.250}$

= $1.836 \mathrm{g} / \mathrm{m}^{3}$

Converting to $m^{3}$ to ml (where $m^{3}$ = 1,000,000 ml)

= $1.836 \times 10^{-6} g / \mathrm{ml}$

lions [2927]

H2PO4- acts as a proton donor, whereas HPO42- serves as a proton acceptor. Step 1: Determining hydrogen ion donors and acceptors in the reaction displayed: H2PO4- is predisposed to release a H+ ion to yield HPO42-. On the other hand, HPO42- is inclined to accept a H+ ion, producing H2PO4-. The process of an acid in a water solvent is characterized as dissociation: HA ⇔ H+ + A- where HA denotes a proton acid. Therefore, H2PO4- = HA and HPO42- = A-. Acids are recognized as proton donors, which is why H2PO4- donates protons and HPO42- accepts them.
