Molar mass of CO2 = 12 + 16*2 = 44 g/mol. Number of moles = mass/molar mass = 44 g / 44 g/mol = 1 mole.

Molar mass of CO2 = 12 + 16*2 = 44 g/mol. Number of moles = mass/molar mass = 44g/44g/mol = 1 mole.

Moles = Molarity x Volume = 2 moles/L x 5 L = 10 moles.

Moles = Molarity x Volume (L) = 2 moles/L x 0.5 L = 1 mole.

The total number of subsets is 2^n = 2^2 = 4. Proper subsets exclude the set itself, so there are 4 - 1 = 3 proper subsets.

The significant figures are 1, 2, 3, and the trailing zero counts.

The significant figures are 4, 5, and 6. Leading zeros are not counted.

The empty set has exactly one subset, which is itself (∅).

The number of subsets of a set with n elements is 2^n. Here, n = 3, so 2^3 = 8.

The number of subsets of a set with n elements is 2^n. Here, n = 5, so 2^5 = 32.

The number of subsets of a set with n elements is 2^n. Here, n = 5, so the number of subsets is 2^5 = 32.

The number of subsets of a set with n elements is 2^n. Here, n = 4, so the number of subsets is 2^4 = 16.

The number of subsets of a set with n elements is 2^n. Here, n = 4, so the number of subsets is 2^4 = 16.

Nyquist rate = 2 * f_max = 2 * 1000 Hz = 2000 Hz = 2 kHz.

Nyquist rate = 2 * f_max = 2 * 5 kHz = 10 kHz.

The Nyquist rate is the minimum sampling rate required to avoid aliasing, which is twice the highest frequency of the signal.

The Nyquist rate is the minimum sampling rate required to avoid aliasing, which is twice the maximum frequency of the signal.

The Nyquist rate is defined as twice the maximum frequency of the signal, which is the minimum sampling rate required to avoid aliasing.
