Answer:

1,545.67

Step-by-step explanation:

step 1

if 1,584 is decreased by 18%

we know that

100\%-18\%=82\%=82/100=0.82

Multiply the number by 0.82

1,584(0.82)=1,298.88

step 2

The number 1,298.88 is increased by a 19%

we know that

100\%+19\%=119\%=119/100=1.19

Multiply the number by 1.19

1,298.88(1.19)=1,545.67

Factors of 42 <br> I need to know what factors make 42
vodomira [7]

<em>1 x 42</em>

<em>2 x 21</em>

<em>3 x 14</em>

<em>6 x 7</em>

Step-by-step explanation:

We need to find factors of 42.

Factors: <em>Two numbers when multiplied if give you the required number then those 2 numbers are factors o that number.</em>

So, Factors of 42 are:

<em>1 x 42</em>

<em>2 x 21</em>

<em>3 x 14</em>

<em>6 x 7</em>

Only these numbers when multiplied will give 42.

So, All these numbers are factors of 42

Butyric acid ( c3h7cooh) is a weak acid . what is the ph of a 0.0250 m solution of this acid. ka = 1.5 x 10-5 (2 decimal places)
Wewaii [24]

The pH of the weak acid is 3.21

Butyric acid is known as a weak acid, we need the concentration of [H+] formula of weak acid which is given by this equation :

[H^{+}]=\sqrt{Ka . Ma}

where [H+] is the concentration of ion H+, Ka is the weak acid ionization constant, and Ma is the acid concentration.

Since we know the concentration of H+, the pH can be calculated by using

pH = -log[H+]

From question above, we know that :

Ma = 0.0250M

Ka = 1.5 x 10¯⁵

By using the equation, we can determine the concentration of [H+]

[H+] = √(Ka . Ma)

[H+] = √(1.5 x 10¯⁵ . 0.0250)

[H+] = 6.12 x 10¯⁴ M

Substituting the value of [H+] to get the pH

pH = -log[H+]

pH = -log(6.12 x 10¯⁴)

pH = 3.21

Hence, the pH of the weak acid c3h7cooh is 3.21
