Based on the data given, the molar mass of the gas is 165.5 g/mol while the molecular weight of the gas is 165.5 amu
<h3>How can molar mass of a gas be obtained from density, temperature and pressure?</h3>
The molar mass of a gas can be obtained from density, temperature and pressure using the formula below:
- molar mass = density × molar gas constant × temperature/pressure
Molar gas constant, R = R = 0.082 L.atm/mol/K.
Temperature = 150 °C = 423 K
Pressure = 785 torr = 1.033 atm
density = 4.93 g/L
molar mass of gas = 4.93 × 0.082 × 423/1.033
molar mass of gas = 165.5 g/mol
Then, molecular weight of the gas = 165.5 amu
Therefore, the molar mass of the gas is 165.5 g/mol while the molecular weight of the gas is 165.5 amu

Answer:
8.3334%
Explanation:
You have two masses. To find the percent of sodium chloride in water by mass, you divide the mass of NaCl by water. First, make both units the same. Easiest is to convert kg into g. 1.5kg = 1500g
125g NaCl/1500g H2O = 0.0833333333 ==> 8.3334%
Answer:

Explanation:
In this case, we have to start with the <u>chemical reaction</u>:

So, if we start with <u>10 mol of cyclohexanol</u> (
) we will obtain 10 mol of cyclohexanol (
). So, we can calculate the grams of cyclohexanol if we<u> calculate the molar mass:</u>

With this value we can calculate the grams:

Now, we have as a product 500 mL of
. If we use the <u>density value</u> (0.811 g/mL). We can calculate the grams of product:

Finally, with these values we can calculate the <u>yield</u>:
%= (405.5/820)*100 = 49.45 %
See figure 1
I hope it helps!
I would say its hydrogen, as it makes 51% of the cell constituents. This is followed by oxygen, which makes up 24% of the cell, and then carbon which is present as 11% of the total mass. Nitrogen makes up 4% of the cell, followed by other elements like phosphorous.
Answer:
Types of chemical weathering
1. Hydrolysis
2. Oxidation
3. Carbonation
4. Acid rain
5. Acids produced by lichens
Explanation:
Chemical weathering occurs when rocks undergo chemical reactions to form new minerals.
Hydrolysis : is when water dissolves minerals present in rocks forming new compounds.
Oxidation : is when oxygen reacts with rocks eg. rust formation
Carbonation : it uses an acid known as carbonic acid, it is important in the formation of many caves and sinkholes.
