An isotope of an element, atomic number Z, has a mass number 2z+4. How many neutrons are there in the nucleus of the element?
DiKsa [7]
A) Z + 4

In the actual atom, half of the nucleus would be protons and the other half neutrons, hence the 2z. The additional four in the expression must be neutrons because adding protons would change the element all together.

How is molarity affected if some solution splashes out of the flask during titration?
Annette [7]
<span>If you used more water, the molarity would go down since molarity is moles/liter, and the opposite if you used more water. 

If the acid absorbed water, the molarity would go down because the absorbed moisture will skew the weight of the acid up. 

That would make the molarity go down since there would have been unreacted acid in the spilled liquid.</span>

I hope my answer has come to your help. Thank you for posting your question here in Brainly. We hope to answer more of your questions and inquiries soon. Have a nice day ahead!

What is the density of a gas with a molar mass of 28.26 grams per mole at 3.510 ATM in 237 Kelvin​
Vikki [24]
<h3><u>Answer;</u></h3>

= 5.1 g/L

<h3><u>Explanation;</u></h3>

Using the equation;

PV = nRT , where P is the pressure,. V is the volume, n is the number of moles and T is the temperature and R is the gas constant, 0.08206 L. atm. mol−1.

Number of moles is 1 since one mole has a mass equivalent to the molar mass.

Therefore; We can find the volume and thus get the density.

<em>V = nRT/P</em>

<em>    = (1 × 0.08206 × 237)/3.510</em>

<em>     = 5.5408 L</em>

<em>Hence; Density = mass/volume </em>

<em>                           = 28.26 g/5.5408 L</em>

<em>                           = 5.1 g/L</em>

<em>The Density is 5.1 g/L or 0.005 g/cm³</em>
