Lemur [1.5K]3 years ago
8 0

Answer:

<h3>The answer is 6.93 cm³</h3>

Explanation:

The volume of a substance when given the density and mass can be found by using the formula

volume =  \frac{mass}{density}  \\

From the question we have

volume =  \frac{26}{3.75}  \\  = 6.93333333...

We have the final answer as

<h3>6.93 cm³</h3>

Hope this helps you

How many molecules (not moles of nh3 are produced from 5.01×10?4 g of h2?
Irina-Kira [14]
2,02g     -------    6,02×10²³
5,01×10⁴g  ---    x

x=\frac{5,01*10^{4}g*6,02*10^{23}}{2,02g}=14,93*10^{27}

N₂         +        3H₂       ⇒           2NH₃
1mol      :        3mol        :           2mol
                       18,06×10²³  :       12,04×10²³
                       14,93×10²⁷  :        y

y=\frac{14,93*10^{27}*12,04*10^{23}}{18,06*10^{23}}\approx9,95*10^{27}

The solubility of co in water at 0c and 1 atm co pressure is 0. 0354 mg of co in 1 ml of water. Calculate the moalrity of aqueso
Dmitriy789 [7]

From all the calculations that were carried out, the concentration of 2atm is 0.0026 M.

<h3>What is molarity?</h3>

The term molarity is defined as the number of moles divided by the volume of the solution. Using the formula; C = kp where

  • C = concentration
  • k = constant
  • p = pressure

C =  0. 0354 * 10^-3 g/28 g/mol × 1000/1 L

C = 0.0013 M

k = C/p = 0.0013 M/1 atm

k = 0.0013 Matm-1

Now;

C =  0.0013 Matm-1 *  2 atm

C= 0.0026 M
