H=(2x1.008)=2.016
O= 15.999
15.999
+ 2.016
______
18.015 g/mol :)
Answer:
The atomic mass is the average number of protons and neutrons for all natural isotopes of an element. It is a decimal number.
Explanation:
Atomic Mass and Mass Number Example
:
Hydrogen has three natural isotopes: 1H, 2H, and 3H. Each isotope has a different mass number.
1H has 1 proton. Its mass number is 1. 2H has 1 proton and 1 neutron. Its mass number is 2. 3H has 1 proton and 2 neutrons. Its mass number is 3. 99.98% of all hydrogen is 1H 0.018% of all hydrogen is 2H 0.002% of all hydrogen is 3H Together, they give a value of atomic mass of hydrogen equal to 1.0079 g/mol.
Answer:
40.79
Explanation:
an ounce is equal to approximately 28.3 grams.
if you have 4 ounces then it would be equal to about 113.4 grams. then you would divide that by 2.78 which will equal about 40.8
When the temperature of a substance decreases to the substance's freezing point, the substance will begin to change from
a liquid to a solid.
The substitution product that is suppose to be favoured is The product with retention of configuration is expected to predominate slightly, because the leaving group blocks the nucleophile.
<h3>What is substitution product?</h3>
Substitution product is a product that is gotten from a reaction in which a group of reactant is replaced by another group in the reaction.
Therefore,The substitution product that is suppose to be favoured is The product with retention of configuration is expected to predominate slightly, because the leaving group blocks the nucleophile.
