Answer:
Mass 1=3M
Mass 2=?
Volume1=75mL
Volume2=250mL
By using molarity formula:
<u>mass1*volume 1=mass2*volume 2</u>
3M*75=mass2*250
mass2=225/250
mass2:0.9M
<h3>the molarity of a solution is 0.9M.</h3>

4. nuclear force
5. they are composite particles
6. proton-positive-inside nucleus; neutron-no charge-inside nucleus; electron-negative-outside nucleus/electron cloud
7. sublevels
8. 4 energy levels
Explanation:
The correct answer is A. Photosynthesis is an exothermic reaction. The reaction releases energy. For the second question, the correct answer is A. Atomic theory is subject to change if new information is discovered. Lastly, the correct answer for the third question is option A. <span>Two nonmetals from Group 16 are likely to form a metallic bond.</span>
