To find the mass of glucose, you must multiply the atomic weight of each of the elements in the molecule by the subscripts in the formula:



Then you add all of them together:

Therefore, the molar weight of glucose is 180.15 grams.
Answer:
the physical property of an object or matter
Answer:
D.
Explanation:
It pushes the experimental results one way or another. Less reliable.
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:
The heat transferred to the system is 1717.322 J
Explanation:
Given data:
n = moles of gas = 1 mol
T = temperature = 25°C = 298 K
Question: Calculate the heat transferred, Q = ?
(volume doubles due the gas expasion)
The heat transferred:

Here
R = ideal gas constant = 8.314 J/mol K
