Answer:

3.05 ×10³ Kg/m³

Explanation:

Density:

Density is equal to the mass of substance divided by its volume.

Units:

SI unit of density is Kg/m3.

Other units are given below,

g/cm3, g/mL , kg/L

Formula:

D=m/v

D= density

m=mass

V=volume

Symbol:

The symbol used for density is called rho. It is represented by ρ. However letter D can also be used to represent the density.

Given data:

Density = 3.05 g/cm³

Density in Kg/m³ = ?

Solution:

In order to convert the g/cm³ to Kg/m³ we will multiply the value with 1000.

3.05 g/cm³ × 1000 Kg/m³ / 1 g/cm³

3050 Kg/m³

In scientific notation:

3.05 ×10³ Kg/m³

What is the millimolar solubility of oxygen gas, o2, in water at 16 ∘c, if the pressure of oxygen is 1.00 atm?

Artyom0805 [142]

Partial pressure is the amount of pressure or force that is exerted by the atoms into the outer environment. it is dependent on the temperature and pressure of the present surroundings. in this case, we are asked in this problem to determine the partial pressure of oxygen at 16oC and 1 atm. We have to look into a solubility data table commonly found in handbooks and determined via experiments and correlations. According to literature, the value of the partial pressure is equal to 0.617 mM.This is under the assumption that the salinity of the water in which oxygen is dissolved is equal to zero.

SpyIntel [72]

Answer: The are bodies of rock or gas that are named for ancient gods.

Explanation:

Earth is the THIRD planet in the solar system. It support life of all living organisms.

VENUS is the second planet in our solar system. It is named after the Roman goddess of love and beauty.

MARS is the fourth planet in our solar system. It is named after the Roman goddess of war.

Thus, Venus and Mars, are EARTH NEIGHBORS

A solution at 25 ∘C has pOH = 10.53. Which of the following statements is or are true? The solution is acidic. The pH of the sol

Lady bird [3.3K]

Answer:

The true statements are:

The solution is acidic

The pH of the solution is 14.00 - 10.53.

$10^{-10.53}=[OH^-]$

Explanation:

The pH of the solution is defined as negative logarithm of hydrogen ion concentration present in the solution .

$pH=-\log[H^+]$

The pH value more 7 means that hydrogen ion concentration is less ,alkaline will be the solution.
The pH value less 7 means that hydrogen ion concentration is more ,acidic will be the solution.
The pH value equal to 7 indicates that the solution is neutral.

The pOH of the solution is defined as negative logarithm of hydroxide ion concentration present in the solution .

$pOH=-\log[OH^-]$

The pOH of the solution = 10.53

$10.53=-\log[OH^-]$

$10^{-10.53}=[OH^-]$

The pH of the solution = ?

$pH+pOH=14$

$pH=14-pOH=14-10.53=3.47$

Here, the pH of the solution is less than 7 which means that solution acidic.

Determine the total number of moles of ions in 40.0 ml of a 0.345 m solution of the strong electrolyte mgcl2

Sedbober [7]

A strong electrolyte like MgCl2 dissociates completely as per the following reaction:

$MgCl_2 ----\ \textgreater \ Mg^{2+} + 2Cl^-$

As you can see, from 1 molecule of MgCl2 produces 3 ions on dissociation.
So, 1 mole of MgCl2 produces 3 moles of ions.

Now, Moles of MgCl2 = Volume x Molarity

= 0.04 x 0.345 [Change volume to Litres]
= 0.0138 moles

Now, total moles of ions = 0.0138 x 3 = 0.0414
