#22 #24 and #26 HELP

Grace [21]

#22)
4(t - 8) + 20 = 5
Distribute the 4.

4t - 32 + 20 = 5
Combine like terms.

4t - 12 = 5
Add 12 to both sides.

4t = 17
Divide both sides by 4.

t = 4.25

#24)
17 = -5(3 + w) + 7
Distribute the -5.

17 = -15 - 5w + 7
Combine like terms.

17 = -8 - 5w
Add 8 to both sides.

25 = -5w
Divide both sides by -5.

w = -5

#26)
9 = -(r - 5) + 11
Distribute the -.

9 = -r + 5 + 11
Combine like terms.

9 = -r + 16
Subtract 16 from both sides.

-7 = -r
r = 7

1)What is the mass of Nitrogen in NH3? (use two decimal places)

Mars2501 [29]

Answer:

1) The Mass of Nitrogen in $NH_3$ is 14.00 gm.

2) The Mass of Hydrogen in $NH_3$ is 3.00 gm.

3)The Molar Mass of $NH_3$ is 17.00 gm.

Step-by-step explanation:

Solving for Part 1.

In $NH_3$ that is Ammonia there is 1 atom of Nitrogen.

So the atomic mass of Nitrogen is same as the mass of Nitrogen in $NH_3$ .

Atomic mass of Nitrogen = 14.00 gm

Hence The Mass of Nitrogen in $NH_3$ is 14.00 gm.

Solving for Part 2.

In $NH_3$ there are 3 atoms of Hydrogen.

Atomic mass of Hydrogen = 1.00 gm

So the mass of Hydrogen in $NH_3$ is 3 times of its atomic mass.

Mass of Hydrogen = 3 × Atomic mass of Hydrogen

$Mass\ of\ Hydrogen =3\times1.00=3.00\ gm$

Hence The Mass of Hydrogen in $NH_3$ is 3.00 gm.

Solving for Part 3.

In $NH_3$ there is 1 atom Nitrogen and 3 atoms of Hydrogen.

So molar mass is the sum of mass of nitrogen and mass of Hydrogen in $NH_3$ .

Molar mass of $NH_3$ =Mass of Nitrogen+Mass of Hydrogen

$Molar\ mass\ of\ NH_3=14.00+3.00=17.00\ gm$

Hence The Molar Mass of $NH_3$ is 17.00 gm.

What is 11.52/128 show your work

grandymaker [24]

Answer:

The answer is

Step-by-step explanation:

11.5/128

First convert the decimal to an improper fraction

That's

$11.52 = \frac{288}{25}$

So we have

$\frac{288}{25} \div 128$

Change the division sign to multiplication sign and reverse the second number

That's

$\frac{288}{25} \times \frac{1}{128}$

Simplify

$\frac{288}{3200}$

Divide through by 32

The final answer is

$\frac{9}{100}$

Hope this helps you
