Step-by-step explanation:
• Molecular mass of carbon dioxide

[ molar masses: C = 12 g, O = 16 g ]
• From avogadro's number, it says 1 mole contains 6.02 × 10^23 molecules or atoms.
But 1 mole is equivalent to its molar mass in terms of weight, therefore;

Answer:
L = 5u
Step-by-step explanation:
area = 8 × L
L = area ÷ 8
40 ÷ 8 = 5
L = 5u
Answer:

Step-by-step explanation:
The slope-intercept form of an equation of a line:

Convert the equation of a line 3x + 4x = 2y - 9 to the slope-intercept form:

<em>add 9 to both sides</em>
<em>divide both sides by 2</em>

Parallel lines have the same slope. Therefore we have the equation:

Put the coordinates of the point (4, -4) to the equation:


<em>subtract 14 from both sides</em>

Finally we have the equation:
