Answer:

Molarity = 0.1678 M

Explanation:

Given data:

Volume = 4.00 L

Mass of KCl = 50.0 g

Molarity = ?

Solution:

Formula:

Molarity = number of moles / volume in L

Number of moles = mass/ Molar mass

Number of moles = 50.0 g/ 74.5 g/mol

Number of moles = 0.8 mol

Molarity = 0.8 mol / 4.00 L

Molarity = 0.1678 M

7. Which of the following represents the largest mass?

Tamiku [17]

Answer:

10kg = 10 x 1000 = 10,000g

Explanation:

To know the quantity with the largest mass, we have to express all the units in grams:

for: 2 x 10mg = 2 x 10 x 10⁻³ = 0.02g

0.001kg = 0.001 x 1000 = 1g

1 x 10⁵ng = 1 x 10⁵ x 10⁻⁹ = 0.0001g

2 x 10²cg = 2 x 10² x 10⁻² = 2g

10kg = 10 x 1000 = 10,000g

Note:

10⁻ ¹ deci(d)

10⁻² centi(c)

10⁻³ milli(m)

10⁻⁹ nano(n)

10³ kilo(k)

The ester below can be separated into phenol and an acetate salt, via saponification: heating the ester with a strong base, such

erastovalidia [21]

I found a similar question online which will help me answer your incomplete question. To make it easier, show all the elements of the compound given. It is shown in the second picture attached.

a.) The formula for unsaturation number is shown in the 3rd picture attached. Following this,
n = 8
m = 2(8) + 2 + 0 + 0 - 0 = 18
Thus,
x = Unsaturation number = (18 - 8)/2 = 5
<em>The unsaturation number is 5.</em>

b.) The molar mass of C is 12.01 g/mol; H is 1 g/mol; O is 16 g/mol. So, the molecular weight is:
Molecular weight = 12.01(8) + 8(1) + 2(16) = 136.08 g/mol
<em>The molecular weight of the ester is 136.08 g/mol.</em>

A fatty acid consists of -COOH bonded to a long chain of:

Sophie [7]

The -COOH is bonded to a long chain of hydrocarbons in a fatty acid.

A hydrocarbon chain is comprised of both carbon (C) and hydrogen (H) atoms. The 'acid' part is made up of the -COOH portion, whereas the 'fatty' part is made up of the long hydrocarbon chain that it is attached to.
