Answer:
92 is that atomic number and 238.03 is the atomic mass number
Explanation:
The structure of the atom is given as:
⁹²₂₃₈.₀₃U
The number 92 is the atomic number of the atom.
The atomic number is the number of protons within an atom. This number defines the nature and type of atom that we have.
238.03 is the atomic mass number;
The is the number of protons and neutrons within an atom. It is typically the mass of nucleus.
Answer:
b) Every experienced cooks at home tend not to use recipes, instead based entirely upon their knowledge of cooking technique.
Explanation:
This is because even the most experienced cooks might make a mistake, so having a recipe where they can follow is better than just use their knowledge. If his or her knowledge has a mistake it might create a big consequence.
Drink lots of water and pain medication
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>
