What is the mass number of an ion with 107 electrons, 159 neutrons, and a +1 charge? express your answer as an integer?
Darya [45]
<span>The mass number of an ion is calculated by adding the neutrons and electrons together. In this case 159+107=266. However, since this ion has a +1 charge, you must add 1 to the electrons. This would give a total mass of 267.</span>

A sample of Hydrogen gas has a volume of 25.5 liters at a pressure of 15.0 kPa. If the temperature is kept constant and the pres
patriot [66]

Answer:

<h2>7.65 litres </h2>

Explanation:

The new volume can be found by using the formula for Boyle's law which is

P_1V_1 = P_2V_2

Since we're finding the new volume

V_2 =  \frac{P_1V_1}{P_2}  \\

15 kPa = 15,000 Pa

50 kPa = 50,000 Pa

We have

V_2 =  \frac{15000 \times 25.5}{50000}  =  \frac{382500}{50000}  \\  = 7.65

We have the final answer as

<h3>7.65 litres </h3>

Hope this helps you

How do sociologists talk about how the individual is related to the larger society?
Viktor [21]

Answer:

Sociologist view that an individual is a reflection of a society to which he or she have belonged.

Explanation:

It is not an individual or a society, but both of them together allows us to reveal the fundamentals of human existence. The extreme view of the person or society has been discarded for quite some time. The concept of society indicates a reciprocal giving-and-take by the individuals involved in the form of mutual corporations, interaction, or the more subtle types of social interaction such as letter writing, festival greeting, sending and accepting presents, telephone communication, e-mailing, internet chatting, and public relations engagement.
