Avolume of 300 milliliters of water is added to a liter of water. what is the final volume of water, in milliliters?
a. 1300 liters
b. 3000 ml
c. 30,000 ml
d. 1300 ml

The final volume of water is 1300 milliliters

Option - d

Solution:

Given the volume of water before adding is 1 liter = 1000 ml

Volume of water added = 300 ml

To find the total volume of water, we have to add both the quantities mentioned above, that is

The total volume of water = 1000 + 300 = 1300 ml

Conversion from liter to milliliter:

To convert liters to ml, we have to multiply the liter value by 1000.

For example: to find out how many milliliters are there in 2 liters we have to multiply 2 by 1000, which makes 2000 milliliters.

assuming that your periodic table has eighteen columns, you should highlight   the four elements in the third column from the left of the table.

neutral atoms of elements after calcium contain d electrons. the energy of d orbitals of a particular main shell lies between the energy of the s and p orbitals of the next main shell. for example, electrons in the have energy higher than those in the orbital while lower than those of the orbital.

by the aufbau principle, electrons fill orbitals one at a time, starting from those of the lowest energy. the orbital is therefore filled right after orbitals and before orbitals.  

potassium has electron configuration and calcium . the s orbital of a main shell holds a maximum of two electrons. the next element would thus have the electron configuration and satisfy the requirements.

a neutral atom of the element contains three electrons on top of the most recent noble gas element. it should thus be placed in the third column of the periodic table. both scandium and yttrium would satisfy the conditions. an aufbau diagram indicates that the 4f orbital is filled before the 5d. however, it appears that exceptions exists for both lanthanum and actinium. neutral atoms of the two d-block elements also demonstrate the and should be highlighted as well.
