Answer:
THE PRESSURE EXERTED BY THE GAS IS THEREFORE 2.88 atm.
Explanation:
Boyle's law states that at constant temperature, the volume of a given mass of gas is inversely proportional to the pressure of the gas.
Mathematically, P1 V1 = P2 V2
Write out the values of the variables given:
P1 = 2.4 atm
V1 = 1.8 L
V2 = 1.5 L
P2 = unknown
Re-arranging the variables by making P2 the subject of the equation, we have:
P2 = P1 V1 / V2
P2 = 2.4 * 1.8 / 1.5
P2 = 2.9=88 atm
Hence, the pressure exerted by the gas is therefore 2.88 atm
Answer:
True
Explanation:
The accuracy level is usually determined by the difference between the experimental and correct value. It is important to note that the smaller the difference between the average experimental value and the correct (true) value, the more accurate it is.
When the difference is large then it means the accuracy level is low and not up to the required standard.
Answer:
c or d it measures smallest to biggest and biggest to smallest
Answer is: molar mass of sodium iodide is 149.89424 g/mol.
Chemical reaction: Na⁺ + I⁻ → NaI.
The molar mass (M)<span> is the </span>mass<span> of a given substance (in this example sodium iodide</span><span>) divided by the </span>amount of substance<span>.
</span>M(NaI) = Ar(Na) + Ar(I) · g/mol.
M(NaI) = 22.98977 + 126.90447 · g/mol.
M(NaI) = 149.89424 g/mol.
