Answer:

The Mitochondria

Explanation:

Mitochondria are membrane-bound cell organelles that generate most of the energy required to power the cell's organic chemistry reactions. Energy created by the mitochondria is kept in a tiny molecule known as adenosine triphosphate (ATP).

Calculate the percent composition by mass of each element in Al(OH)3. Use at least three significant figures.

allsm [11]

Answer:

34.59 % Al; 61.54 % O; 3.877 % H

Explanation:

% by mass = mass of element/total mass × 100 %

Let's rewrite the formula of Al(OH)₃ as AlO₃H₃.

Set up a table for easy calculation.

Atom Mass/u Subtotal

1Al 1 × 26.98 = 26.98 u

3O 3 × 16.00 = 48.00 u

3H 3 × 1.008 = 3.024 u

Total = 78.004 u

Mass % Al = 26.98/78.004 × 100 % = 34.59 %

Mass % O = 48.00/78.004 × 100 % = 61.54 %

Mass % H = 3.024/78.004 × 100 % = 3.877 %

Harrizon [31]

Answer:

Carbon

Explanation:

$\frac{(98.9*12)+(1.1*13)}{100}$

the answer gives you 12.011 which is closer to the amu of carbon

Butane C4H10, is an easily liquedfied gaseous fuel. calculate the density of butane gas at 0.897 atm and 24°C. give the answer i

yawa3891 [41]

Answer:

Density = 2.137 gram per liter (Approx.)

Explanation:

Given:

Gaseous fuel Butane C4H10

Pressure = 0.897 atm

Temperature = 24°C = 24 + 273 = 297 k

Find:

Density of butane gas

Computation:

We know that molar mass of butane = 58.12 g/mol

Density = [molar mass x pressure] / Rt

Density = [58.12 x 0.897] / [0.0821 x 297]

Density = [52.13] / [24.3837]

Density = 2.137 gram per liter (Approx.)
