The molarity of the Isopropanol solution is 1.68 M.

<h3>How we calculate molarity?</h3>

Molarity of any solution can be calculated as:

M = n/V, where

n = no. of moles

V = volume = 1,250mL = 1.250L

For this first we have to calculate the moles of Isopropanol (C₃H₈O), and it can be calculated as:

n = W/M, where

W = mass of C₃H₈O = 127 grams

M = molar mass of C₃H₈O = 60.1 g/mol

Moles of C₃H₈O = 127g / 60.1 g/mol = 2.1 moles

Now, we calculate the molarity of solution by using the above formula and by putting values as:

M = 2.1/1.250 = 1.68 M

Hence, 1.68 M is the molarity of the solution.

What happens if a acid hits aluminum​
satela [25.4K]

Answer:

Acids that form a complex with aluminum ions can eat their way through the oxide coating, however, so concentrated hydrochloric acid can dissolve aluminum. Zinc is also very reactive and lacks the passivating layer found on aluminum, so it reduces hydrogen ions from acids like hydrochloric acid to form hydrogen gas.

Calculate the volume occupied by 55.5 moles of water at STP.
Tems11 [23]

Answer:

Volume occupied by 55.5 moles of water gas at STP = 1240 Liters.

Explanation:

1st keep in mind that 'volume' in the context of problems like this apply only to the gas phase form of the substance. Water in solid form (ice) or liquid form (liquid water) do not apply. Volume in this case is referred to as 'molar volume' and is a gas occupying 22.4 liters at STP conditions (0°C, 1Atm).

So, if 1 molar volume of water gas (steam) occupies 22.4 Liters at STP, then 55.5 moles of water gas occupies 22.4 Liters/mole x 55.5 moles = 1243.2 Liters, or 1240 Liters (3 sig. figs.).   :-)

In which orbital does an electron in a bromine atom experience the greatest effective nuclear charge?
asambeis [7]

First let us determine the electronic configuration of Bromine (Br). This is written as:

Br = [Ar] 3d10 4s2 4p5

 

Then we must recall that the greatest effective nuclear charge (also referred to as shielding) greatly increases as distance of the orbital to the nucleus also increases. So therefore the electron in the farthest shell will experience the greatest nuclear charge hence the answer is:

<span>4p orbital</span>
