<u>Answer:</u> The pressure of carbon dioxide gas is 11 atm
<u>Explanation:</u>
To calculate the pressure of gas, we use the equation given by ideal gas equation:
PV = nRT
where,
P = pressure of the gas = ?
V = Volume of gas = 25 L
n = number of moles of gas = 10 mole
R = Gas constant = 
T = temperature of the gas = 325 K
Putting values in above equation, we get:
Hence, the pressure of carbon dioxide gas is 11 atm
The distance from one point to another is the distance traveled by a light beam between them.
If you have the coordinates of the 2 points, then the distance between them is
√ of [ (the difference in their x-values)² + (the difference in their y-values)² ]
Answer:
3 × 10¯¹⁰
Explanation:
9×10² ÷ 3×10¹²
The above expression can be evaluated as follow:
9×10² ÷ 3×10¹²
Recall:
3² = 9
3¹ = 3
Therefore,
9×10² ÷ 3×10¹² = 3²×10² ÷ 3¹×10¹²
Recall:
y^m ÷ y^n = y^(m – n)
Therefore,
3²×10² ÷ 3×10¹² = 3²¯¹ × 10²¯¹²
= 3¹ × 10¯¹⁰
Recall:
y¹ = y
Therefore,
3¹ × 10¯¹⁰ = 3 × 10¯¹⁰
Therefore,
9×10² ÷ 3×10¹² = 3 × 10¯¹⁰
