Q. What is the result of multiplying 6.02 x 10^23 by 3.0, considering significant figures?
A.
1.8 x 10^24
B.
1.806 x 10^24
C.
1.80 x 10^24
D.
1.8060 x 10^24
Solution
In multiplication, the result should have the same number of significant figures as the factor with the least significant figures. 6.02 x 10^23 has 3 significant figures and 3.0 has 2, so the answer should be 1.8 x 10^24.
Q. What is the result of subtracting 5.00 from 10.0, considering significant figures?
A.
5.0
B.
5
C.
5.00
D.
5.000
Solution
In subtraction, the result should be rounded to the least number of decimal places. 10.0 has one decimal place and 5.00 has two, so the result should be rounded to one decimal place: 5.0.
Q. What is the result of subtracting 5.678 from 10.0, considering significant figures?
A.
4.32
B.
4.3
C.
4.4
D.
4.00
Solution
In subtraction, the result should be rounded to the least number of decimal places. 10.0 has one decimal place and 5.678 has three, so the result should be rounded to one decimal place: 4.32 becomes 4.3.
Q. What is the RMS speed of an ideal gas in terms of its temperature and molar mass?
A.
sqrt((3RT)/M)
B.
sqrt((2RT)/M)
C.
sqrt((RT)/M)
D.
sqrt((3M)/RT)
Solution
The RMS speed (v_rms) of an ideal gas is given by the formula v_rms = sqrt((3RT)/M), where R is the universal gas constant, T is the absolute temperature, and M is the molar mass.
Q. What is the RMS speed of an ideal gas in terms of temperature and molar mass?
A.
sqrt((3RT)/M)
B.
sqrt((RT)/M)
C.
sqrt((3kT)/m)
D.
sqrt((2RT)/M)
Solution
The RMS speed (v_rms) of an ideal gas is given by the formula v_rms = sqrt((3RT)/M), where R is the universal gas constant, T is the temperature in Kelvin, and M is the molar mass.
