Answer : 58.44 g
<h3>Further explanation</h3>
The reaction
mole ratio :
Na : Cl : NaCl = 1 : 1 : 1
Molar mass of Na : 22,989769 g/mol = 22.99 g/mol
Molar mass of Cl : 35,453 g/mol= 35.45 g/mol
Molar mass of NaCl : 58,44 g/mol
Let's check the mol for reactant (Na and Cl) and product(NaCl)
Then the reactants are completed reacting because it matches the mole ratio, which is 1: 1
so that the mole of the product can be determined from the mol Na or Cl, which is 1
Answer:
The percent composition is 21% N, 6% H, 24% S and 49% O.
Explanation:
1st) The molar mass of (NH4)2SO4 is 132g/mol, and it represents the 100% of the mass composition.
In 1 mole of (NH4)2SO4, there are:
- 2 moles of N.
- 8 moles of H.
- 1 mole of S.
- 4 moles of O.
2nd) It is necessary to calculate the mass of each element, multiplying its molar mass by the number of moles:
- 2 moles of N (14g/mol) = 28g
- 8 moles of H (1g/mol) = 8g
- 1 mole of S (32g/mol) = 32g
- 4 moles of O (16g/mol) = 64g
3rd) With a mathematical rule of three we can calculate the percent composition of each element in the molecule of (NH4)2SO4:
In this case, we can calculate the percent composition of Oxygen by subtracting the other percentages, since the total must be 100%.
So, the percent composition is 21% N, 6% H, 24% S and 49% O.

Answer:
See below!
Explanation:
Solids have a definite mass, a definite shape, and a definite volume. They are not compressible and are the most tightly packed together.
Liquids have definite mass and definite volume. Liquids take up the shape of the container and are not compressible. They are slightly packed together but are allowed to move freely.
