<u>Answer:</u> The final volume of the gas comes out to be 4 L.
<u>Explanation:</u>
To calculate the volume with changing pressure, we use the equation given by Boyle's law.
This law states that pressure is inversely proportional to the volume of the gas at constant temperature and number of moles.
Mathematically,
(At constant temperature and number of moles)
The equation given by this law is:
where,
are initial pressure and volume.
are final pressure and volume.
We are given:
Putting values in above equation, we get:
Hence, the final volume of the gas will be 4 L.
673.5 in scientific notation would be 6.735 X 10^2.
Answer:
Do you have options of answers for this question
Explanation:
1mM of solution means millimolar, that is 1 millimole of solute is contained in 1 liter of solvent.
Converting mM to M,
150mM to M = 150*1 x 10^-3
= 0.15M
Number of moles = molar concentration * volume
= 0.15*0.5
= 0.075 moles.
Molar mass of NaCl = 23 + 35.5
= 58.5 g/mol
Mass of NaCl = molar mass * number of moles
= 58.5*0.075
= 4.3875g
Description:
• 4.3875 g of NaCl is measured on a measuring scale and poured in a conical flask.
• 1 liter of solvent is measured with a measuring cylinder and poured into the conical flask and mixed.
