EastWind [94]

Answer:

c. 56

Explanation:

Convert molecules --> moles --> grams

1.2 x 1024 molecules CO * 1 mol/6.022 x 1023 molecules * 28.01 g/1 mol = 55.8153438

Rounded is 56

Let me know if you need further explanation!!

The mass of each WtWt isotope is measured relative to C−12C−12 and tabulated below. Use the mass of C−12C−12 to convert each of

Nadya [2.5K]

The question is incomplete , the complete question is;

The mass of each Wt isotope is measured relative to C-12 and tabulated below. Use the mass of C-12 to convert each of the masses to amu and calculate the atomic mass of Wt.

Wt-296 = 24.6622

Answer:

The atomic mass of Wt-296 is 195.9464 amu.

Explanation:

1 amu is defined as 1 by twelfth of the carbon-12 mass.

Mass of an isotope Wt-296 = 24.6622

Mass of an isotope Wt-296 in amu = M

$M\times \frac{1}{12 amu}=24.6622$

$M=24.6622\times 12 amu=295.9464 amu$

The atomic mass of Wt-296 is 195.9464 amu.
