For which compound does 0.256 mole weigh 12.8 g?
mylen [45]
Number of moles = \frac{mass (g)}{Molar mass}
so to calculate molar mass (Molecular weight of compound):
Molecular weight = \frac{mass (g)}{number of moles}
            = \frac{12.8 g}{0.256 mole} = 50 g / mole
Now we calculate molecular weight of each compound in choices:
a) C₂H₄O = 44
b) CO₂ = 44
c) CH₃Cl = 50.4 ALMOST 50  so this is the correct answer
d) C₂H₆ = 30

Calculate the amount in moles of 125 g of CaSO4.
Leto [7]

Answer:

Number of moles = 0.92 mol

Explanation:

Given data:

Mass of CaSO₄ = 125 g

Number of moles of CaSO₄ = ?

Solution:

Formula:

Number of moles = mass/ molar mass

Molar mass of CaSO₄:

Molar mass of CaSO₄ = 40 + 32+ 16×4

Molar mass of CaSO₄ = 40 + 32+ 64

Molar mass of CaSO₄ = 136 g/mol

Number of moles:

Number of moles = mass/ molar mass

Number of moles = 125 g/ 136 g/mol

Number of moles = 0.92 mol

As pH increases, what happens to the hydrogen ion concentration?
levacccp [35]

Answer:

According to libretexts the answer would be B. decreases.

Explanation:

If the hydrogen concentration increases, the pH decreases, causing the solution to become more acidic. This happens when an acid is introduced. ... If the hydrogen concentration decreases, the pH increases, resulting in a solution that is less acidic and more basic
