This problem is providing information about the moles of carbon dioxide, 2.76 mol, and asks for the volume this amount takes up, turning out to be 61.8 L according to the Avogadro's law:
<h3>Avogadro's law:</h3><h3 />
In chemistry, gas laws are used to relate the behavior of gases by virtue of the their pressure, volume, temperature and moles; thus several gas laws exist for us to do so, however, we here focus on the Avogadro's law which relates the volume and moles when both temperature and pressure are held constant.
In such a way, since no information on the constant variables is given, we assume the mentioned carbon dioxide is at STP, (0 °C and 1 atm), which means that we can use the following equivalence statement derived from the ideal gas law (PV=nRT):
22.4 L = 1 mol
Hence, we calculate the required volume:

Answer:
4 mL
Explanation:
Data Given:
Density (d) = 4.8 g/mL
Mass of the substance (m) = 19.2 g
Volume of the sample (V) = ?
Solution:
Formula will be used
d = m/V
As we have to find volume so rearrange the above equation
V = m/d . . . . . . . . . . . (1)
Put values in above equation 1
V = 19.2 g / 4.8 g/mL
V = 4 mL
So,
volume of sample = 4 mL

Answer:
D. a relatively small fraction of the maximum number of possible hydronium ions.
Explanation:
A weak acid is an acid that is partially dissociated into its ions in an aqueous solution or water. A weak acid is one that does not dissociate completely in solution; this means that a weak acid does not donate all of its hydrogen ions (H+) in a solution
It is produced when an Arrhenius acid dissolves in water. So a weak acid would form a relatively small fraction of the maximum number of possible hydronium ions while in contrast a strong acid would form a relatively large fraction of the maximum number of possible hydronium ions.
I've tried this like, probably 10 times, it never worksbut ig we'll see
