Answer:
2.13atm
Explanation:
The following information were obtained from the question:
P1 (initial pressure) = 2atm
T1 (initial temperature) = 27°C = 27 + 273 = 300K
T2 (final temperature) = 47°C = 47 + 273 = 320K
P2 (final pressure) =?
Using the equation P1/T1 = P2/T2, the final pressure within the tyre can be obtained as illustrated below:
P1/T1 = P2/T2
2/300 = P2/320
Cross multiply to express in linear form
300 x P2 = 2 x 320
Divide both side by 300
P2 = (2 x 320)/300
P2 = 2.13atm
Therefore, the pressure within the tyre at 47°C is 2.13atm
Answer:
824 g
Explanation:
First we <u>convert 7.0 x 10²⁴ formula units of magnesium chloride (MgCl₂) into moles</u>, using <em>Avogadro's number</em>:
- 7.0 x 10²⁴ formula units ÷ 6.023x10²³ formula units/mol = 11.62 mol MgCl₂
There are two Cl moles per MgCl₂ moles, meaning that we have (2 * 11.62) 23.24 moles of Cl
Finally we <u>convert 23.24 moles of chlorine into grams</u>, using <em>chlorine's molar mass</em>:
- 23.24 mol * 35.45 g/mol = 824 g
Answer is D organs because cell forms tissues, tissues form organs and organs forms the organ system
