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)

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

What volume of 0.550 M KBr solution can you make from 100.0 mL of 2.50 M KBr?

castortr0y [923]

M1V1 = M2V2
(2.50)(100.0) = (0.550)V2
V2 = 455mL

From 100.0 mL of 2.50 M KBr, you can prepare 455 mL of 0.550 M solution.

If the density of carbon tetrachloride is 1.59 g/ml, what is the volume in l, of 4.21 kg of carbon tetrachloride

Tems11 [846]

Density is defined as the mass-to-volume ratio. The formula for density can be expressed as:

$density = \frac{mass}{volume}$ -(1)

The density for carbon tetrachloride is provided as $1.59 g/ml$ (given).

The mass of carbon tetrachloride is $4.21 kg$ (as given).

Since, $1 kg = 1000 g$

Thus, $4.21 kg = 4210 g$

Utilizing the values in formula (1):

$1.59 g/mL = \frac{4210 g}{volume}$

$volume = \frac{4210 g}{1.59 g/mL}$

$volume = 2647.799 mL$

Since, $1 mL = 0.001 L$

Hence, $2647.799 mL = 2.65 L$

The resulting volume of carbon tetrachloride is $2.65 L$ .

Next we need to determine the mass of oleic acid in the monolayer. The concentration of the oleic acid/benzene solution is 0.02g

Alekssandra [968]

Response:

$m=1x10^{-6}g$

Clarification:

Hello,

In this scenario, since a single drop equates to 0.05 mL of the solution provided, with a concentration of 0.02 g/mL, the mass of oleic acid in one drop calculates to:

$m=0.02\frac{g}{L}*0.05mL*\frac{1L}{1000mL}\\ \\m=1x10^{-6}g$

Best wishes.

A chemist is studying the following reaction: NO + NO2 ⇌ N2O3. She places a mixture of NO and NO2 in a sealed container and meas

castortr0y [923]

Answer:

The forward reaction will keep occurring until all NO or all NO₂ is consumed.

Clarification:

According to Le Châtelier's principle, when a system at equilibrium experiences a disturbance from an outside source, the system will adjust to counteract this disturbance and restore equilibrium.

Thus, removing the product (N₂O₃) from the system effectively lowers the product concentration, prompting the reaction to shift forward and generate additional product in order to alleviate the strain caused by the removal of N₂O₃.

Consequently, the reaction will proceed forward until all of either NO or NO₂ is depleted.

The speed of light in a vacuum is 2.998 × 10 8 8 m/s. How long does it take for light to circumnavigate the Earth, which has a c

castortr0y [923]

Answer:- 0.134 seconds

Solution:- The speed is given as $2.988*10^8\frac{m}{s}$ and the circumference is 24900 miles which is same as the distance light have to covered. It asks to calculate the time required to cover this distance by the light.
